Abstract

The study of fission yields has a major impact on the characterization and understanding of the fission process and is mandatory for reactor applications. While the yields are known for the major actinides (²³⁵U, ²³⁹Pu) in the thermal neutron-induced fission, only few measurements have been performed on ²⁴²Am. This paper presents the results of a measurement at the Lohengrin mass spectrometer (ILL, France) on the reaction ²⁴¹Am(2n_th,f): a total of 41 mass yields in the light and the heavy peaks have been measured and compared with the fission process simulation code GEF. Modus operandi and first results of a second experiment performed in May 2013 on the same reaction but with the goal of extracting the isotopic yields are presented as well: 8 mass yields were re-measured and 18 isotopic yields have been investigated and are being analyzed. Results concerning the kinetic energy and its comparison with the GEF Code are also presented in this paper.
