英文摘要 | Excited states in V-55 and Cr-55 have been populated via pn and 2n evaporation channels, respectively, following the fusion of a Ca-48 beam at 172 MeV with a Be-9 target. Level schemes have been deduced for the two nuclides to excitation energies of 7467 (V-55) and 12226 keV (Cr-55), with spins of 27/2(+) and 33/2(+), respectively. Negative-parity states are compared with shell-model calculations using three different effective interactions in the full fp model space. Negative-parity levels of Cr-55 are explained in terms of single-particle fp-shell configurations outside N = 28 and N = 32 cores. Positive-parity states in both isotopes show evidence for the involvement of neutron g(9/2) configurations. In the case of Cr-55, a quasirotational structure based on the 1/2(+)[ 440] Nilsson orbital is observed up to the terminating state. In V-55, positive-parity states do not exhibit well-developed collective features, and the observation of octupole decays is an indication of their importance in transitions from neutron g(9/2) configurations to the fp shell. Experimental results are compared with the predictions of a traditional shell model, the projected shell model, and total-Routhian-surface calculations. |
