WebWe will be comparing with the 'semi-empirical mass formula'. To do this, we must convert from 'mass excess' to 'binding energy'. The binding energy is the mass of N neutrons and Z protons minus the nuclear mass. The 'mass excess' is the atomic mass minus (N+Z) atomic mass units, where an atomic mass unit is 1/12 of a carbon 12 atom.

WebUsing such analogy, the semi-empirical mass formula (also known as the Bethe-Weizaecker formula), was derived from the liquid drop model empirically as a function of mass number A and atomic number Z as shown in Figs. 1 and 2. [3] Fig. 2: The semi-empirical mass formula with coefficients (±10% error) determined experimentally. [5] Web7. The nuclear landscape: In this question, we will use the semi-empirical mass formula to explore the limits of nuclear stability. For simplicity in parts (c), (d) and (e), we’ll ignore the pairing term by setting aP = 0 and let Z(Z −1) ≈ Z2 for the Coulomb term. (a) Recall from class how we derived an expression for the so-called “valley of stability” by setting
