Selective population of the n=3 level of hydrogen-like carbon in two colliding laser-produced plasmas

Phys. Lett. A 225 (1997) 107-112
The possibility is investigated that charge exchange collisions between ions of a hot plasma (C6+) and a cold plasma (C2+) is responsible for selectively enhanced emission of the C5+ Balmer-alpha line emitted from the interaction zone of the two colliding laser-produced plasmas.

resonant charge exchange normal charge exchange
Workshop “Ultrashort pulse laser-plasma interactions”, Prague, September 24-27, 2003
We shall explain the three features:
1. why does excitation/ionization remain large2. Why the charge exchange is ‘narrower’3. The behaviour of the resonant cross section

If there is any resonant or quasi-resonant process,it will dominate
We have explained these three features:
