Abstract The de-excitation of levels in119–125Sn populated in the decay of In isotopes has been studied using on-line isotope separators. Level half-lives have been measured in119–123Sn. a near cancellation of the matrix element for B(E2; g7/2→ d3/2) is observed to occur in121Sn and is probably due to pairing effects. Very low lying 9/2− levels have been observed in121–125Sn and are suggested in127, 129Sn. These levels have been interpreted as three quasi-particle states based on the unique parity h11/2 level. A possible mixing of theg 7/2 level with a close lying 7/2+ three quasi-particle state in123Sn is discussed.
