I. Research experience: 12 yrs 11 months (PhD – 5yrs, 3PDF – 4yr 1m, Faculty – 3 yr 10m)

(A) Ph.D thesis related works at Saha Institute of Nuclear Physics

(Sept 2003 – Aug 2008, 5 yrs):

The title of my Ph.D thesis is “Shell structure and evolution of collectivity on and away from the stability line” (Ph.D

supervisor – Prof. Maitreyee Saha Sarkar, Saha Institute of Nuclear Physics). This thesis comprises the study of two

regions of doubly closed shell nuclei over the nuclear chart: stable nuclei with N ~ Z around 40Ca and highly neutron-rich

ones close to drip-line above the 132Sn shell closure. Both experimental and theoretical works have been done for each

of these mass regions. The experimental part includes three works: (i) high energy characterisation of the Compton

suppressed Clover detector, (ii) In-beam gamma-ray spectroscopic studies of high spin states of 35Cl in mass 40 region

and (iii) X- and gamma- ray spectroscopic studies of fission fragments of 252Cf spontaneous fission source in mass 132Sn

region. The theoretical study supplemented the experimental findings using the microscopic Shell model and the

phenomenological Particle Rotor model. A brief summary of my works is given below.

A1. Setup and developmental work:

(i) For the high energy (5 MeV < E < 10MeV) characterisation of Compton suppressed Clover detector, we performed an

experiment at Institute of Physics (IOP), Bhubaneswar using 13C(p, γ)14N and 27Al(p,γ)28Si resonance reactions. Along with

the full energy photopeak efficiency, the addback factor and the hit pattern were determined as a function of gamma-

ray energies. The addback factors show a sharp increasing trend even at around 10 MeV. Efficiency of Clover in addback

mode has been compared with those of a standard HPGe detector. Our results have provided crucial information on the

efficiency of such detectors at high energies and have shown the advantage of using composite detectors over normal

HPGe detectors for high energy discrete gamma-ray spectroscopy. This work has been done as a prelude to our

experimental study of mass 40 region using a Clover array. (Principal Investigator: Prof. M. Saha Sarkar)

(ii) I have actively participated in setting up of the Indian National Gamma

Array (INGA), at the Variable Energy Cyclotron Center (VECC), Kolkata

during August 2004 and August 2005. This array comprised of 6 and later 8

Compton-suppressed Clover detectors. Various collaborative experiments

along with the one for studying mass 170 region and the experiment using 27Al(16O, xαypzn) reaction for studying mass 40 region (details in section B4

below) were performed using this setup.

(iii) I have actively participated in setting up of the 7 Compton-suppressed Clover detector array, at TIFR, Mumbai during

January 2007. Two experiments – one using 27Al(14N, xαypzn) reaction, for studying mass 40 region and another – a

collaborative experiment (details in section B4 below) were performed using this setup.

A2. Study of mass 40 region:

We have studied A~ 40 region using the 12C(28Si, xypzn), 24Mg(16O, xypzn) and 27Al(16O, xypzn) fusion-evaporation

reactions performed at Tata Institute of Fundamental Research (TIFR), Inter University Accelerator Centre (IUAC) and

Variable Energy Cyclotron Centre (VECC) using the Indian National Gamma Array (INGA) setup of 6 and 8 Compton-

suppressed Clover detectors. Level schemes are built up for 35,37Cl and 30P along with extraction of level lifetimes using

coincident Doppler Shift Attenuation Method (DSAM). Other spectroscopic information like DCO (Directional Correlation

of Oriented states) ratio, Polarization asymmetry (IPDCO), Side-feeding intensity and time have been extracted. Large

4

basis cross-shell Shell model calculations have been done to interpret all these results. The side-feeding intensity pattern

have been interpreted in terms of the statistical model of compound nucleus. The work on 35Cl nucleus is directly related

to my thesis. (P.I: Prof. M. Saha Sarkar)

A3. Study of neutron-rich nuclei in 132Sn region:

(i) Gamma-ray spectroscopy experiment of fission fragments: For studying the exotic nuclei near 132Sn, I have worked in

an in-house off-line gamma-ray spectroscopy experiment with 252Cf spontaneous fission source using two Compton

suppressed Clovers and Clover-LEPS coincidence setup. Since a highly efficient detector system is essential for studying

the prompt gamma-rays emitted from the fission fragments, we performed experiments with these simple set-ups for

checking the feasibility of doing such experiments. By using a coincidence condition between LEPS and gamma ray

detector, we got rid of L X-rays of 248Cm, thereby clearly observing the X-rays from the lighter fragments which couldn’t

be seen earlier. From the two Clover set-up, we could identify a few gamma-rays from the existing level schemes of

some of Te and Xe isotopes. This work is done as a review coursework during Post-MSc. (P.I: Prof. M. Saha Sarkar)

(ii) Theoretical study of evolution of collectivity in the neutron-rich nuclei in 132Sn region: Motivated by the observed

regularity in the energy spectra and the structure of the shell model wave functions (which show configuration mixing)

for the levels of 137Te and 137I, a few weakly and moderately deformed neutron-rich odd-A nuclei (137I, 137Te, 139I, 139Te, 139Cs, 139Xe, 141Xe, 141Ba) above the doubly magic nucleus 132Sn have been studied using the Particle Rotor Model. The

calculated energy spectra and branching ratios agree reasonably well with the most recent experimental data. In a few

cases ambiguity in level ordering has been resolved and spin-parities have been assigned to the levels. This work also

started as a part of review coursework during Post-MSc.

(B) Other works initiated / performed during doctoral tenure:

(Sept 2003 – Aug 2008, 5 yrs):

Along with my Ph.D work, I have been involved in various investigations of our gamma-ray spectroscopy group. A brief

summary of these works is given below.

B1. Study of mass 170 region: We have studied A~ 170 region using 159Tb(16O, xαypzn) reaction performed at VECC using

the above mentioned INGA setup. Several nuclei like 167,168Lu, 168-170Hf, and 169-171Ta have been populated. Preliminary

results of the lifetimes of two isomeric levels of 169Ta using the centroid shift method of electronic timing technique, are

in good agreement with the adopted values. The structure has been studied using the Particle Rotor Model. Theoretical

results agree very well with experimental findings and are acting as a guide in building the level scheme. (P.I: Prof. M.

Saha Sarkar)

B2. Low – background measurements: Comparison of various

background characteristics of normal HPGe and the Clover detectors

has been done using both passive and active shielding. A symmetric

BGO and asymmetric NaI(Tl) shield has been used for the 25% HPGe

detector while a standard symmetric BGO shield has been used for the

Clover detector. We have tried to observe the dependence of these

characteristics on the particular environment, detector and electronics

used. This work will be relevant for the FRENA (Facility for Research in

Experimental Nuclear Astrophysics) project. (P.I: Prof. M. Saha Sarkar)

5

B3. Study of spin-orbit interaction over the whole periodic table across the valley of stability: We have theoretically

studied the spin-orbit splitting near all magic numbers as well as near a few sub-shell closures for protons as well as

neutrons from the available data. We have observed that for Z<40 - the spin-orbit splitting increases as one moves away

from line of stability. For 40<Z<83, the splitting decreases as a function of |N – Z|. Again for Z=83, the trend reverses.

Also for neutrons, the splitting shows a similar variation. At present a paper is being written.
