Collective bands in 125I

An in-beam gamma-ray spectroscopic study of the nuclear structure of I-125 has led to extensions and alterations of the level scheme of this nucleus. Several new intraband and interband transitions are observed in the positive parity bands based on pi d(5/2) and pi g(7/2) configurations, indicating mixing of the two configurations in these bands. The strongly coupled pi g(9/2) band has also been extended and characteristic quadrupole crossover transitions, hitherto unreported, have been observed, providing estimates of the B(M1;I-->I-1)/B(E2;I-->I -2) ratios fdr transitions in this band. New experimental results are presented concerning the three-quasiparticle structure and likely members of the unfavored signature of the prolate pi h(11/2) band, showing excellent agreement with the theoretical results. Experimental results are discussed in relation to the systematics of the neighboring odd-A nuclei. [S0556-2813(99)07605-0].
