Description
By using a non-relativistic independent particle approach we investigate the mechanism promot- ing 34 as new magic number. We carried out Hartree-Fock plus Bardeen-Cooper-Schrieffer and Quasi-particle Random Phase Approximation calculations by consistently using the same finite- range interaction in all the three steps of our approach. We used two Gogny-like interactions, with and without tensor terms. We find that the shell closure for N = 34 neutrons appears in isotones with proton number smaller than 26. The smaller is the proton number, the more evident is the shell closure at N = 34. An ideal nucleus to investigate this effect is 48Si , as it has been recently suggested.
