Abstract
Weak levels in the compound nucleus were located by neutron time-of-flight spectroscopy techniques. Neutron capture measurements were performed with both a natural cadmium target and a highly enriched target. A total of 22 new resonances were located in the neutron energy interval 20-500 eV and were assumed to be p-wave. Resonance parameters, and g, are given for the newly identified levels. The p-wave strength function was determined to be =2.8±0.8 and the average level spacing 〈〉=14 eV. Comparison of the reduced widths with a Porter-Thomas distribution is consistent with having missed 15% of the p-wave levels.
