Abstract

Precise thermal neutron capture γ-ray cross sections σγ were measured for all elements with Z=1-83,90, and 92, except for He and Pm, at the Budapest Reactor. These data were evaluated with additional information from the literature to generate the Evaluated Gamma-ray Activation File (EGAF). Isotopic radiative neutron cross sections can be deduced from the total transition cross section feeding the ground state, σ0= Σσγ(GS) if the decay scheme is complete. The EGAF file contains partial γ-ray cross sections for all stable palladium isotopes. None of these decay schemes are complete, although in each case transitions de-exciting low-lying levels are known. We have performed Monte Carlo simulations of the palladium thermal neutron capture decay schemes using the computer code DICEBOX. The simulated populations of low low-lying levels are normalized to the measured σγ values from EGAF and the total radiative neutron cross section σ0 is obtained. The σ0 values derived for the palladium isotopes agree well with previous measurements and were in several cases more precise. Complementary use of γ-ray cross-section data and Monte Carlo calculations has proven effective in determining both the palladium total radiative cross sections and new nuclear structure information.
