Abstract

A measurement is described of partial radiative widths of neutron resonances of Cr-53. Neutron energy is selected by time-of-flight and gamma energy is measured by a Ge-crystal with anticoincidence shielding. Partial widths are measured for single s-wave resonances from 4 to 30 keV. An improved Average Resonance Capture method is applied to p-wave resonances from 13 to 70 keV. Transition probabilities are obtained to final states with excitations up to 4.3 MeV. A new method is described to deduce absolute values of rγi/rγ. Estimates are obtained of E1 and M1 strengths and of their energy dependence.
