Title: Measurements of the mass and isotopic yields of the {sup 233}U(n{sub th},f) reaction at the Lohengrin spectrometer

Abstract

Over the last 10 years, a vast campaign of measurements has been initiated to improve the precision of neutron data for the involved key nuclei ({sup 232}Th, {sup 233}Pa and {sup 233}U) of the innovative Th -{sup 233}U cycle. This latter might indeed provide cleaner nuclear energy than the present U-Pu one. New measurements of charge and mass distributions of the fission products have been achieved at the Lohengrin spectrometer of the Inst. Laue-Langevin (ILL) during fall 2010 to complete the experimental data of {sup 233}U(n,f) that exist mainly for light fission fragments. That is why we performed measurements of mass and isotopic yields with a special focus on the heavy fission fragment part. Mass yields were measured by ion counting with an ionization chamber after separation by the Lohengrin spectrometer. Isotopic yields were derived from gamma spectrometry of mass-separated beams using HPGe clover detectors. This paper will present the results of these fission yield measurements along with details on the experimental set-up and the chosen analysis method. (authors)
