- Abstract
High-seniority excitations above the 10+ and 27/2- isomeric states were investigated with gamma coincidence techniques in neutron-rich Sn isotopes produced in fission processes following 48Ca+208Pb, 48Ca+238U and 64Ni+238U reactions. In the data analysis, the delayed gamma coincidence technique was used to establish high-spin state structures in all Sn isotopes with isomeric half-lives below 10 µsec. For cases with long-lived isomeric states, the gamma cross-coincidence method was employed to identify such structures. The relevant features of the fusion-fission process were investigated to enable these identifications. The discussion of some details of these analyses is followed by two examples of the results obtained: the 124Sn level scheme and the level energy systematics for selected states established in even Sn isotopes.
