DISINTEGRATION OF SN113,

Abstract

A reinvestigation of the decay of 119-d tin-113 was carried out with scintillation as well as with lithium-drifted silicon- and germanium-detectors. In addition to X rays, two gamma rays of 0.2555 plus or minus 0.0005 and 0.3910 plus or minus 0.0005 MeV were found in relative intensity (2.9 plus or minus 0.3)x0.01. The K-conversion coefficient of the 0.2555-MeV transition was measured to be 0.042 plus or minus 0.010 and that of the 0.3910-MeV one, 0.49 plus or minus 0.04 (K/LM=4.2 plus or minus 0.4). The electron-capture ratio P sub EC (LM...)/P sub EC(K) to the 0.6465-MeV level of indium-113 was determined to be 0.36 plus or minus 0.20. The bremsstrahlung end-point energy to the same level was (0.080 plus or minus 0.005) MeV. From these values the decay-energy transitions to that level was deduced to be 0.050-0.170 MeV and (0.110 plus or minus 0.005) MeV, respectively. A decay scheme is constructed and reasonable shell-model as well as microscopic models assignments are made to all levels. (Author)
