Location of a doorway state using the channel n+/sup 207/Pb

The location of a doorway state in the n+/sup 207/Pb channel is established through a statistical analysis of the observed partial widths for gamma-rays and neutrons. Several statistical tests developed to help locate doorway states are presented. The statistical analysis focuses on the strong correlation between large partial widths in the two exit channels. Widths in both exit channels exhibit extremely large values in the energy region near E/sub n/ = 120 keV. This clustering of large widths, even when considered separately for each exit channel, is relatively unlikely to occur in a statistical sample. The strong correlation between channels decreases the likelyhood for this clustering of large widths to occur in a statistical sample to less than 0.0003
