Development of shell closures atN=32,34. I.βdecay of neutron-rich Sc isotopes

Abstract
Details regarding the β-decay properties of Sc54,55,56 are reported and compared with shell model predictions. The low-energy level structures of even-even Ti54,56 are presented, and the systematic variation of the energy of the first excited 21+ state is discussed in light of proposed shell closures at N=32,34 for the neutron-rich Ti isotopes.
