Evaluation of the ~(125)Sb nuclear decay data

摘要

Evaluation of the complete decay scheme and data for ~(125)Sb/~(125m)Te decay to nuclear levels in ~(125)Te is presented in this report; literature data available up to June 2015 are included. The Limitation of Relative Statistical Weight Method (LRSW) was applied to average numbers throughout the evaluation. The uncertainty assigned to the average value was always greater than or equal to the smallest uncertainty of the values used to calculate the average. The half-life has been determined to be 1007.4 ± 03 days. All known measured γ-ray absolute or relative intensities have been examined; the γ-ray emission probability of the reference γ-ray line of 427.874 keV is recommended to be 29.54 ± 0.10%. The theoretical internal conversion coefficients and their uncertainties were used to obtain the complete decay scheme intensity balance. The values of other decay characteristics were calculated using the ENSDF analysis program Finally the updated decay scheme for ~(125)Sb is presented.
