Abstract : T HE (neutron, 2 neutron) cross sections for Re-187 and Re-185 were measured with 14.1 Mev neutrons from the T(deutron, neutron)He4 reaction. The standard used was Au-197. Since the (n,2n) reaction with Au-197 results in Au-196 and Au-196 (excited level) with half-lives of 5.3 days and 14 hours, respectively, the cross section for Au-196 was used as the standard. The cross section for Re-187(n,2n)Re-186 was found to be 1.44 ! 0.41 barns. An upper limit for the Re-185(n,2n)Re-184 cross section was found to be 1.80 ! .60 barns. The decay of Au-196 (excited level) proceeds via isom ric transition to Au-196. (Author)
