Photoionitation of H2

  1. Mar 12, 2013 #1
    How come that in photoionitation of H2 molecule we have multiple (>2) ionization thresholds? Is there any good literature on this matter?

    Because electrons can occupy more than 1 state.

    Each state has its own ionization threshold.

    Thanks tor answer Claude!

    If you are referring to the multiple low energy ionization limits, they are due to the excitation of one electron to threshold, along with vibrational and/or rotational excitation of the resulting ion core.

    In fact I was referring to doubly excited resonant states!
