1In the case of electron capture and internal conversion, the chemical environment

of the electrons involved may affect the decay rate. For L-electron capture in7Be (t!=

53.3d), the ratio of is 1.00084. Similarly, a fully stripped radioactive ion cannot

undergo either EC or IC decay, a feature of interest in astrophysics.

2In order to make this statement completely correct, we should say that as we

double the number of nuclei present, we double the rate of particle emission. This rate isequal to the number of particles emitted per unit time, provided that the time interval is

small.
