摘要:

We report on the low‐energy structure of the neutron‐rich, even‐even nuclides54Ti32,56Cr32, and58Cr34studied via &bgr;‐delayed &ggr;‐ray spectroscopy. The systematic variation of the excitation energy of first excited 2+states in the even‐even24Cr and22Ti isotopes provides evidence of a subshell closure atN= 32 for neutron‐rich nuclides having Z ⩽ 24. Shell model calculations, which correctly account for the appearance of theN= 32 subshell, also predict a new shell closure atN= 34 for Ti and Ca isotopes. © 2003 American Institute of Physics
