摘要：
Evaluation of the complete decay scheme and data for Ac-225 including new measurements are presented in this report; literature data available up to March 2006 are included. The half-life is determined to be 10.0 +/- 0.1 days. All known measured gamma-ray relative intensities have been examined; the gamma-ray emission probability of the reference gamma-ray line of 150.04keV is recommended to be 0.693 +/- 0.012%. 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 225 Ac is presented. (C) 2007 Elsevier Ltd. All rights reserved.
