Abstract
We study extrapolation approaches to evaluate energies of low-lying states for nuclei in the and shells, by sorting the diagonal matrix elements of the nuclear shell-model Hamiltonian. We introduce an extrapolation method with perturbation and apply our new method to predict both low-lying state energies and transition rates between low-lying states. Our predicted results arrive at an accuracy of the root-mean-squared deviations –60 keV for low-lying states of these nuclei.
