| 英文摘要 | New level schemes of Ba-141 and Xe-139 are proposed from analysis of the gamma data from Cf-252 spontaneous fission in Gammasphere. By analogy with the N=85 even-odd isotones Gd-149, Sm-147, and Nd-145, spins and parities were assigned to the observed excited states in Ba-141 and Xe-139. Level systematics in the N=85 even-odd isotones from Gd (Z=64) to Te (Z=52) are discussed. The level systematics and comparison with neighboring even-even isotopes indicate that quadrupole and octupole collectivities play a role in Ba-141 and Xe-139. From Gd (Z=64) to Te (Z=52), increasing excitation energies of the 13/2(+) states and lowering relative intensities of the positive-parity bands in the N=85 even-odd isotones may indicate that the octupole strength is becoming weaker for the isotones when approaching the Z=50 closed shell. |
