For the (positron) emission from a nucleus, there is another competing process known as electron capture (electron from an inner orbit, say, the K shell, is captured by the nucleus and a neutrino is emitted).

Show that if  emission is energetically allowed, electron capture is necessarily allowed but not vice versa.

Solution: Consider the competing processes:
(positron cature)
(electron capture)
 




This means implies , but  does not necessarily mean
