The high-spin structure above the previously known 10+ isomers of the 118, 120,122, 124Sn isotopes was studied via prompt γ-ray spectroscopy. All isotopes were populated as fragments following the fission of much heavier compound nuclei formed in three fusion-fission reactions. The 118, 120,122, 124Sn isotopes were also independently populated and studied as evaporation residues in the 124Sn(n, xnγ) 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 118, 120,122, 124Sn, respectively. The experimental results are compared with predictions from shell-model calculations.
