A Mass Formula with a Few Free Parameters and Nuclear Mass Calculations

  • A mass formula with deformation and shell corrections for a few free parameters was described.By means of the formula the calculations of 1440 nuclear masses and 1250 two neutron separation energies s2n in the region of 28≤Z≤81 were performed.The root-mean-square deviations are respectively 1.01MeV for nuclear masses and 0.57MeV for s2n.The results of the theory could also reproduce the characters of the closure shell,the subshell and the deformation of the nuclei.

Abstract: A mass formula with deformation and shell corrections for a few free parameters was described.By means of the formula the calculations of 1440 nuclear masses and 1250 two neutron separation energies s2n in the region of 28≤Z≤81 were performed.The root-mean-square deviations are respectively 1.01MeV for nuclear masses and 0.57MeV for s2n.The results of the theory could also reproduce the characters of the closure shell,the subshell and the deformation of the nuclei.
