Use the result given in part a to determine the differential scattering cross-section and show it to be d(e)= 167d, esin (0/2) from part a b-(gn/8no, e) cot (0/2) this is the impact parameter for the collision between charged particles based on the coulomb potential. this is from classical theory, not qm. c) show the total cross-section for rutherford scattering is infinite note: understanding the way charged particles interact impacts many areas of physics and technology. this interaction covers any ion-ion collision, which is exactly how electrons move about in a material to conduct electricity, for example. the fact the cross-section is infinite for this case limits the use of many approximations regarding localized potentials
