Paper Abstract

A search of Nuclear Excitation by Electron Transition (NEET) in 235U excited in the plasma produced by a 300 mJ, 10 ns laser is presented. Many experimental aspects have been faced to evidence the low rate of NEET excitation of the 76 eV isomeric level in 235U with a plasma temperature T=25 eV. The experimental limit measured for the transition rate for the 76 eV 235Um state is (lambda) N<2.10-5s-1. Several potential upgrades are considered to aim at a measure of the NEET excitation rate in 235$U.
