摘要：

The high-spin structure above the previously known 10(+) isomers of the Sn-118,Sn-120,Sn-122,Sn-124 isotopes was studied via prompt gamma-ray spectroscopy. All isotopes were populated as fragments following the fission of much heavier compound nuclei formed in three fusion-fission reactions. The Sn-118,Sn-120,Sn-122 isotopes were also independently populated and studied as evaporation residues in the Sn-124(n, xn gamma) reactions, with x = 3, 5, 7. Transitions above the previously known 10(+) isomers were observed for the first time and the corresponding level schemes above these isomers were established up to 6646-, 5673-, 5386-, and 5952-keV excitation energy for Sn-118,Sn-120,Sn-122,Sn-124, respectively. The experimental results are compared with predictions from shell-model calculations.
