The fact that BE/A is greatest for A near 60implies that the range of the nuclear force is about the diameterof such nuclides.
(a) Calculate the diameter of an A = 60 nucleus.
________ fm
(b) Calculate BE/A for 56Fe and102Ru. The first is one of the most tightly boundnuclides, while the second is larger and less tightly bound.
56Fe
________ MeV
102Ru
________ MeV
