Abstract

Recent results obtained for neutron-rich nuclei of mass A 60-70 are presented together with the theoretical interpretation. The development of a new region of deformation approaching the neutron number N = 40 in Cr and Fe isotopes is discussed. A new effective interaction that considers the full fp shell model space for protons and the p(3/2), p(1/2), f(5/2), g(9/2), d(5/2) orbitals for the neutrons allows to reproduce, for the first time, the different structure properties of these nuclei. The configuration of the calculated states suggests the development of a new island of inversion at N 40. The perspectives offered by the forthcoming operation of the AGATA Demonstrator Array coupled to the magnetic spectrometer PRISMA at LNL are also discussed.
