Beta decay, electron capture Q value

  1. Apr 30, 2016 #1
    1. The problem statement, all variables and given/known data
    Find the ##Q## value for electron capture of ##^{196}Au##.

    2. Relevant equations
    ##Q_\epsilon = [m(^AX)-m(^AX')]c^2-B_n##

    3. The attempt at a solution
    How do I know if I have an ##K##- or ##L##-shell for the electron?
    Assuming I have an ##K## shell taking ##B_n = \; ^{196m1}Au## from this table,
    https://en.wikipedia.org/wiki/Isotopes_of_gold
    ;I get the correct answer but I don't understand why it couldn't just as well been an ##L##-shell?

    Capture from the innermost shell is by far the most likely process.

    Thanks! That would make sense out of it.
