Abstract Isomeric decays in116, 118, 120Sn and119, 120Sb have been studied by measurements of delayedγ-rays following reactions of 26–40 MeV7Li ions on Cd targets. A 6.3 μs isomer of $$(vh_{11/2} ^n )^{10 + } $$ character in120Sn is reported. The experimental variation inB(E2, 10+ → 8+) between $$vh_{11/2} ^n $$ states in116, 118, 120, 128, 130Sn is compared with the expected dependence on vh11/2 subshell occupation number. Isomerism in Sb nuclei is also discussed, and a known high-spin isomer in119Sb is assigned the same seniority-three configuration $$(\pi d_{5/2} vh_{11/2} ^n )^{25/2 + } $$ as a well-established 340 μs isomer in117Sb.
