← Iron has 26 protons in its nucleus. A 5.2 MeV alpha particle runs head-on into an iron nucleus. How near to the centre of the nucleus does it come before it stops? Use e²/4πε₀ = 1.44 MeV fm.A head-on hit would bring an alpha particle to within 52 fm of a nucleus. A second alpha particle of the same energy passes with its original path 15 fm from the nucleus. Through what angle does it turn? →
