This is a classical mechanics problem, and Rutherford worked it out when he was trying to figure out alpha-nucleus scattering. https://en.wikipedia.org/wiki/Rutherford_scattering The equation is the one directly *above* the section header "Details of calculating maximal nuclear size". For proton-proton scattering, Z=1. -- Odd Bodkin --- maker of fine toys, tools, tables
