Status of fission fragment observables measured with the LOHENGRIN spectrometer

A general status of the experimental program using the gamma spectrometry with the LOHENGRIN mass spectrometer at the ILL has been presented. Recent results for thermal neutron induced fission of ²⁴¹Pu have been presented. The gamma spectrometry method, in particular for the Converted Isomeric Ratios, considers the nuclear structure as the basic data allowing the study of a large timescale of isomeric states as probe of the fission process. In this topic, the development of the FIPPS project at ILL is dedicated to fission product spectroscopy and fission process studies. Classical measurements of fission yields are now expanded with their kinetic energy dependency in order to test the limit of fission models
