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. So WebJan 22, 2024 · Recall the mass of nuclide as given by the semi-empirical mass formula. If we keep A fixed, the SEMF gives the binding energy as a function of Z. The only term that depends explicitly on Z is the Coulomb term. By inspection we see that B ∝ Z 2. Then from the SEMF we have that the masses of possible nuclides with the same mass number lie … chihuly rose tree

WebNov 9, 2024 · The semi-empirical mass formula for the binding energy of a given nuclide, as a function of atomic number, Z, and atomic mass number, A, was derived independently by Carl von Weizsäcker [ 28] in 1935 and Hans Bethe [ 29] a year later. The formula is also known as the Bethe–Weizsäcker mass formula.
