Isotopic and Isomeric Yields Measurement in the Near Symmetric Mass Region of the 241Pu(nth,f) Reaction
We propose to investigate isotopic and isomeric yields from 241Pu thermal neutron induced reaction, in the heavy mass region (close to the symmetry): A=125 up to A=134. For that, fission products selected by Lohengrin will be implanted in a moving tape placed inside a vacuum chamber. Then, two ILL clover Ge detectors will be used to measure gamma-rays which follow beta-decays of fission products. In this way, the contributing nuclear charges can be identified. This method has already been applied successfully to measure isotopic yields of 239Pu(n_th,f) and 233U(n_th,f) reactions. This proposal is motivated for both nuclear energy applications and the expected improvement of our fission process understanding.
