Coincidence spectroscopy of the [sup 186]W(n,xnypzαγγ) reaction using the KEGS array at LANSCE/WNR

Several γ-γ coincidence measurements have been performed using “beams” of spallation neutrons from the LANSCE/WNR facility. Because these reactions have low multiplicity, a geometrically compact detector arrangement was used to enhance the coincidence rate. The data taken with a target of 186W proved to be the most useful, as several new levels were identified in both 186W and 185W. Additionally, the reactions generated with the high energy neutrons (En>200 MeV) revealed the production of nuclei as remote from 186W as 170W, 166Hf, and 160Yb.
