Abstract
Capture cross sections of the chromium isotopes have been measured at neutron energies up to 350 keV using the capture cross section facility at the 40 m station of the Oak Ridge Electron Linear Accelerator.
Parameters have been derived for 180 resonances. A moderate correlation [p(г0n,гγ) - 0.45] is observed between reduced neutron widths n y and radiative widths for s-wave resonances. Calculations of valence widths show that valence capture can only account for the correlated component of the observed radiative widths. An additional mechanism such as a 2p-lh doorway state must therefore be occurring to explain the uncorrelated component.
