Attempt for Revision of JNDC FP Decay Data File

摘要

Some improvement of JNDC FP Decay Data File is tried by reexamining the decay scheme for several nuclides, since slight discrepancies are seen in detailed comparison of decay powers. As a result, it is found that the average beta- and gamma-energies should be modified for sup 88 Rb and sup 143 La among the nuclides reexamined in the present study. The JNDC file modified in sup 88 Rb and sup 143 La gives better agreement in most cases with experiments than the original JNDC file for cooling times longer than a few thousands seconds. Howver, the discrepancy for cooling times from a few hundreds to about 1500 seconds still remains. 10 refs., 27 figs. (ERA citation 11:030913)
