The nuclear radius of gold is approximately r = 7.0 fm (1.0 fm = 1.0 x 10-15 m). The radii of protons and a particles are 1.3 fm and 2.6 fm, respectively. (a) What energy a particles would be needed in head-on collision for the nuclear surfaces to just touch? (This is about where the nuclear force becomes effective.) (b) What energy protons would be needed?
