A What Are the Final Electronic and Ionic States of 72Ga After Decay to 72Ge?

[Malamala]

Hello! I see that $^{72}$Ga decays exclusively to $^{72}$Ge by electron emission. I couldn't find however any paper describing the final electronic state of the $^{72}$Ge atom. I assume that the electron emitted just escapes, and the resulting $^{72}$Ge atom is actually an ion? Also the decay to $^{72}$Ge can happen to many levels, followed by the emission of gamma rays. Are these rays further ionizing the $^{72}$Ge ion thus the final state of $^{72}$Ge can have multiple ionic states? Thank you!

That's the most likely outcome, yes.

That is possible, although it's probably less likely.

The FINAL state is surely the ground state. But the IMMEDIATE state can be lots of things - you've just injected many, many times the ionization energy into the system. It's easy to knock out an electron, and impossible to predict which one.

Sooner or later it will neutralize and de-excite.

By a large but predictable margin:

The prediction from back in 1961 is that for neutron (decay energy 782 keV), the probability of decaying into a bound protium atom is 4,2*10^-6, of which 80% is into ground state of hydrogen and 20% into all excited states. For tritium atom (decay energy 18 keV), the probability of decaying into a bound He-3 atom is 6,9*10^-3 (0,69%), of which 78% is into ground state and 22% into excited states.

That is possible, although it's probably less likely.

For any specific decay event.
Is it possible to predict the absorption/excitation spectrum of an atom for its own decay radiation, whether gamma, beta (easier?) or alpha or fission?
