1. The problem statement, all variables and given/known data Refer to the decay scheme of 137Cs What is the value of the internal‐conversion coefficient 2. Relevant equations α = Ne/Nγ Ne=number of conversion electrons Nr=number of competing gamma photons for that transition 3. The attempt at a solution α = Ne/Nγ =2/1 a=2 The correct answer is 0.118. I am unable to figure out the problem.
