“…The 246.9 keV level is the favored candidate for the state with the 3/2 + ͓411͔ configuration suggested by Lhersonneau et al [39] based on the systematic study of the levels in the 101 Sr, 103 Zr, and 105 Mo isotones. This also is assumed by Liang et al [40]. The population of these two excited states were observed in the present work.…”

Neutron-rich Zr and Mo isotopes were populated as fission fragments produced by the 238 U͑␣, f͒ fusionfission reaction. The level schemes of these nuclei have been extended beyond the first band crossing region, which can be ascribed to the h 11/2 neutron pair alignment. The spin alignment and signature splitting for the h 11/2 orbitals in term of triaxiality is addressed. The crossing frequency of the aligned bands in even Zr and Mo isotopes can be reproduced well by calculations using the cranked shell model. Compared to the Zr isotopes, band crossings in Mo isotopes shift to a lower rotational frequency due to the emerging importance of the ␥ degree of freedom. Within the framework of particle-rotor model, the difference in the signature splitting observed for the h 11/2 bands between the odd Zr and Mo isotopes can be attributed to the triaxial degree of freedom in the Mo isotopes. The surprising shift of the band crossing to a higher rotational frequency in 106 Mo is interpreted as a manifestation of the deformed subshell closure at N = 64.

“…Also, in a number of Ru and Mo isotopes, side-bands have been studied [9,14,[21][22][23]. High-spin states in odd-A nuclei have been found in 101 Sr [24], 101 Zr [25], 103 Zr [26], 101 Nb [27], 103 Nb [28], 103 Mo [29], 105 Mo [30], 103 Rh [31], and 109,111 Ru [32]. For the heavy Sr isotopes, spectroscopic studies [33,34] are still in a preliminary stage, and practically nothing is known on the neighboring Kr and Se nuclei.…”

Equilibrium shapes and high-spin properties of the neutron-rich A ≈ 100 nuclei

1997

Shapes and high-spin properties of nuclei from the neutron-rich (N >56) zirconium region are calculated using the Nilsson-Strutinsky method with the cranked Woods-Saxon average potential and monopole pairing residual interaction. The shape coexistence effects and the competition between rotationally-aligned 1h 11/2 neutron and 1g 9/2 proton bands is discussed. Predictions are made for the low-lying superdeformed bands in this mass region, characterized by the intruder states originating from the N =5 and 6 oscillator shells.PACS number(s): 21.10.
