I have a question about cross section probability for a positron (e+) to interact with the electron (e-) that would be bound to three different atomic systems (1) hydrogen atom: H(e-), (2) deuterium atom: D(e-), (3) tritium atom: T(e-).
My hypothesis is that a positron (e+) would have the highest cross section interaction probability with H(e-) and lowest with T(e-), with D(e-) intermediate. My thinking is that the addition of neutrons in the D and T systems would serve to slightly shield the positron (e+) and (e-) wavefunctions from forming unstable positronium, thus lower cross section probability of interaction between the (e+) and (e-). Would my hypothesis be correct ?
