Binding energies in (1d, 2s) shell nuclei

Abstract

Binding energies of nuclei throughout the (1d, 2s) shell were calculated with a modified surface delta interaction. The full energy matrices within the complete space of all configurations containing 1 d 5 2 , 2 s 1 2 and 1 d 3 2 protons and neutrons were diagonalized. In spite of the crudeness of the interaction used, fair agreement is obtained between calculated and experimental energies. In particular, the calculated curve of α-particle separation energies shows kinks closely following the experimental ones.
