Description
The de-excitation of levels in 119-125Sn populated in the decay of In isotopes has been studied using on-line isotope separators. Level half-lives have been measured in 119-123Sn. A near cancellation of the matrix element for B(E2;gsub(7/2)→Dsub(3/2)) is observed to occur in 121Sn and is probably due to pairing effects. Very low lying 9/2- levels have been observed in 121-125Sn and are suggested in 127129Sn. These levels have been interpreted as three quasi-particle states based on the unique parity Hsub(11/2) level. A possible mixing of the Gsub(7/2) level with a close lying 7/2+ three quasi particle state in 123Sn is discussed. (Auth.)
