Homework Help: Electron capture

  1. Oct 30, 2011 #1
    1. The problem statement, all variables and given/known data

    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.

    2. Relevant equations


    3. 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 ?

    Can someone at least give me a small hint or a link to some books/web-pages ?
    I have searched my literature on this, but I'm not sure that I even understand the problem.
