Three recoil studies of the system 120 MeV "C + ='U have been performed, one measuring the cross section of 49 fission products, the second, the angular distribution of 33 of them, and the third, the differential range distribution of the same 33. Using the recoil velocity of the intermediate nucleus as a signature of the projectile-target interaction, the cross section, angular anisotropy, and kinetic energy measurements have been divided into complete and incomplete fusion contributions. About 30% of the cross section may be accounted for by incomplete fusion, most probably of an n-particle. Angular anisotropies are calculated for both complete and incomplete fusion components for each of the individual products. A method is introduced for the reconstruction of fission events based on the measured energies of individual products and is used to determine kinetic energy distributions in the two types of processes.
The TRISTAN research program is briefly outlined. The discussion then turns to the measurements of magnetic moments of excited states in neutron-rich fission product nuclei using the perturbed angular correlation method. The results for 2 + y states are analyzed in light of the systematics of magnetic moments in the A=70-200 region, and in relation to collective nuclear models.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
