Evaluation of 235U decay data

Evaluation of the complete decay scheme and data for ²³⁵U including new measurements are presented in this report; literature data available up to June 2008 are included. The half-life is determined to be (7.04±0.01)×10⁸ yr. All known measured γ-ray absolute intensities have been examined; the γ-ray emission probability of the reference γ-ray line of 185.72 keV is recommended to be 57.0±0.3%. The calculated internal conversion coefficients and their uncertainties have been used to obtain the complete decay intensity balance. The other decay characteristics are calculated using the ENSDF analysis program. Finally the new decay scheme for ²³⁵U is presented.
