The atomic mass of Argon 37 (Z=18, N=19) is 36.9668 u, and
the atomic mass of Chlorine 37 (Z=17, N=20) is 36.9659 u. Questions:
1.
Can Chlorine 37 beta decay to Argon 37 (with emission of an electron)?
Give a reason for your answer.
2.
Can Argon 37 beta decay to Chlorine 37 (with emission of a positron)?
Again, give a reason.
3.
Can Argon 37 decay to Chlorine 37 by electron capture? Again -- a
reason!
