An autoionizing state of a poly-electron atom (or molecule) is one in which at least two electrons are excited, such that when one electron returns to its former state, the other can become ionized.
If one could turn off the electron-electron repulsion in the Helium atom i.e.,

and one created from ground state Helium an autoionizing state 2s3p, what would be the kinetic energy (positive definite) of the emerging electron?
The reaction is:


He(2s3p) -> He+(1s) + e-(``free'')
(The assumption is that both electrons in neutral Helium see the full nuclear charge, i.e., no shielding.)
