If we were to consider a nucleon-nucleon interaction:(adsbygoogle = window.adsbygoogle || []).push({});

We know that the incident wave (plane wave) is ψ= Ae[itex]^{ikz}[/itex], propagating in z direction

But for some mathematical facilities, we tend to use spherical coordinates, the wave becomes = [itex]\frac{A}{2ik}[/itex][e[itex]^{ikr}[/itex]/r - e[itex]^{-ikr}[/itex]/r]

How come?

Where did the '2ik' in the denominator come from?
