Abstract : A reinvestigation of the decay of 119d tin113 was carried out with scintillation as well as with lithiumdrifted silicon and germaniumdetectors. 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 Kconversion coefficient of the 0.2555MeV transition was measured to be 0.042 plus or minus 0.010 and that of the 0.3910MeV one, 0.49 plus or minus 0.04 (K/LM=4.2 plus or minus 0.4). The electroncapture ratio P sub EC (LM...)/P sub EC(K) to the 0.6465MeV level of indium113 was determined to be 0.36 plus or minus 0.20. The bremsstrahlung endpoint energy to the same level was (0.080 plus or minus 0.005) MeV. From these values the decayenergy transitions to that level was deduced to be 0.0500.170 MeV and (0.110 plus or minus 0.005) MeV, respectively. A decay scheme is constructed and reasonable shellmodel as well as microscopic models assignments are made to all levels. (Author)
