Some aspects of the decay scheme of 54 minute 116In

Abstract

The gamma rays following the decay of 54 min 116In were examined with the help of scintillation spectrometers. A detailed analysis of the direct spectrum was performed. Coincidence relations were established by the summing method. The results were found to be in agreement with those reported by Sltis, duToit and Siegbahn4). The existence of the disputed 1.8 MeV gamma ray was confirmed and a level at 3.07 MeV in 116Sn is proposed as the origin of this gamma ray. The presence of a 3.08 MeV peak in the summing spectrum supports this, interpretation.
