There is a type of exchange of particles which is generalised by a type of potential:(adsbygoogle = window.adsbygoogle || []).push({});

[itex]\frac{e^{-\alpha\r}}{R}[/itex] This potential is used to explain the exchange of bounded particles (e.g a poin between neutron and proton) between two possible configurations. The potential comes from the fact that the momentum of the bounded particles is imaginary.

for instance: p=i sqrt(mp*E) I have problem understanding the meaning of a imaginary momentum.

Could the forum explain me what an imaginary momentum means in QM?
