Measurements of the 86Kr(n ,γ ) 87Kr and 86Kr(n ,2 n ) Kr85m reaction cross sections below En=15 MeV
Abstract
The 86Kr(n ,γ ) 87Kr neutron-capture cross section was measured at 11 energies between 0.37 and 14.8 MeV. Cross-section data for the 86Kr(n ,2 n ) Kr85m reaction were obtained at 9 energies between 10.9 and 14.8 MeV. The data are important for testing calculations used to predict the s -process cross section in the unmeasured energy range above 1 MeV for the 86Kr(n ,γ ) 87Kr reaction, and to check on the consistency of parameters used in talys calculations for the 86Kr(γ ,n ) Krm+g85 cross section. The two data sets could also be used as a nuclear physics based diagnostic tool for studying properties of the deuterium-tritium plasma created in inertial confinement fusion reactions at the National Ignition Facility at Lawrence Livermore National Laboratory.
