Text Solution

Verified by Experts

The correct Answer is:
(a) `(0.693)/(14xx60)=8.25xx10^(-4)s^(-1)`
(b) `( m_(n)-m_(p)-m_(e ))931=782 keV`

Staements I: In alpha decay of different radioactive nuclides, the energy of alpha particles has been compared. It is found that as the energy of alpha particle increases the half-life of the decay goes on decreasing. Staements II: More is the energy in any decay process, more is the probability of decaying the nuclide which leads to faster rate of decay.
