Consider a process of a capture of an electron into 2p1/2 and 2p3/2 states of hydrogen atom.
Find a population ratio of these two states after the capture.
The Attempt at a Solution
I don't know where to start on this question. As far as I know, electron capture is a process where
Inner electron is absorbed by a nucleus (proton or neutron), and not captured into a into 2p1/2 and 2p3/2 states.
And what is meant by population ratio ?
