Fragment yields from the fission of ²³⁸U by fast neutrons

Abstract:

Independent yields of post-neutron emission, secondary fragments from the fission of ²³⁸U induced by fast neutrons have been measured using γ-γ coincidence data. The yields of these products are found to be centred on more neutron-rich isotopes than the yields from fission processes previously used for spectroscopic studies on neutron-rich nuclei. The average angular momentum in the fragments is found to be similar to that in fragments formed in other low-energy fission processes.
