## Abstract

The level structure of ^{235}U has been studied by secondary γ-rays and their conversion coefficients, following thermal neutron capture in ^{234}U. A level scheme containing 39 levels was established; 12 levels have been assigned to the following configurations, resulting from the coupling of quasi-particle states to vibrational excitations of the core: {left open angle bracket}[631↓]+0^{+}{right open angle bracket}, {left open angle bracket}[631↓]-2^{+}{right open angle bracket}, {left open angle bracket}[631↓]+0^{-}{right open angle bracket}, {left open angle bracket}[622↑]+0^{+}{right open angle bracket}, {left open angle bracket}[622↑]-2^{+}{right open angle bracket}. The excitation energy of the 1 2^{+} isomeric state was found to be 74±4 eV, which is of considerable interest in the understanding of the electronic structure of UO_{2}.
