Abstract
Total thermal radiative neutron cross sections have been measured on natural and enriched isotopic targets containing , and with neutron beams from the Budapest Reactor. Complete neutron capture -ray decay schemes were measured for each isotope. Absolute transition probabilities have been determined by a least-squares fit of the transition intensities, corrected for internal conversion, to the decay schemes. The -ray cross sections were standardized using stoichiometric compounds containing both the isotope of interest and another element whose -ray cross sections are well known. Total cross sections were then determined for each isotope from the -ray cross sections and transition probabilities. For the reaction decay transition probabilities were determined for the rays from ( ms) decay.
