| 英文摘要 | In-beam gamma spectroscopy of the stable nucleus I-127 has been studied experimentally using the Sn-124(Li-7, 4n gamma) I-127 reaction at a beam energy of 32 MeV. The high-spin level scheme of I-127 is extended significantly. Negative-parity levels built on the 11/2(-), pi h(11/2) particle state are observed up to (35/2(-)) and described as a decoupled band, extending our knowledge of decoupled structures to the most neutron-rich stable iodine isotope. Two Delta I = 2 yrast positive-parity sequences are proposed to be associated with the pi g(7/2) configuration due to observations of several strong interband transitions, and two weakly populated Delta I = 2 positive-parity bands are newly identified and interpreted as arising mainly from the pi d(5/2) configuration. Three-quasiparticle configurations are assigned to the I-pi = 15/2(+) and 23/2(+) states according to the existing knowledge in neighboring nuclei; irregular noncollective and regular collective excitations built on these two (15/2(+) and 23/2(+)) states are observed to coexist at similar energies. The observed three-quasiparticle band structures are further interpreted with the aid of configuration-constrained potential energy surface calculations. |
