Measurements of fission fragments in the interaction of 19F + 181Ta system at 115 MeV

This paper details the cross-section measurements of 38 fission-like events in 19F + 181Ta system at energy 115 MeV, originating from complete and/or incomplete fusion-fission processes. The recoil-catcher off-beam activation technique followed by γ-ray spectroscopy has been used to measure production cross sections of fission-like events. The measured cross-section data of fission-like events align well with Gaussian distributions indicating their production via de-excitation of equilibrated compound nucleus formed. Additionally, the study explores mass and isotopic yield distributions of fission fragments, with the presently measured isotopic yield variance which is found to be consistent with literature values for other fissioning systems.
