Q1. The Bethe-Weizsacker formula (Semi empirical mass formula) provides an excellent representation of the mass systematics of nuclei. Show explicitly that, for fixed A, M(A, Z) has a minimum value. Is there evidence for the "valley of beta stability"? What is the stablest nucleus with A = 16? What about A = 208?
