Study of the 243Am decay

Abstract Gamma-ray emission probabilities for 243 Am were published in 1996. Three new gamma transitions were then found: 46.84, 98.36 and 102.02 keV. In the last evaluation by the Decay Data Evaluation Project, the emission probabilities of 46.84 and 102.02 keV transitions were not included. Alpha-gamma coincidence measurements have been now used to check and revise the values for these two transitions and their emission probabilities. The emissions of the 31.13, 43.53, 74.66, 86.71 and 141.89 keV transitions were also studied.
