1.	Forthe (positron) emission from a nucleus, there is another competingprocess known as electron capture (electron from an inner orbit, say,the K−shell, is captured by the nucleus and a neutrino isemitted).Showthat if emission is energetically allowed, electron capture is necessarilyallowed but not vice−versa.
Answer» 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.

Answer»

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.
