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 ²³⁵U^m 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.
