Measurement of residues from the 6Li+Zn reaction: Analysis of fusion phenomena below 7.1 MeV/nucleon

摘要

We report the measurement of fusion-evaporation residues emerging from 6Li +Zn reaction within the 21-43 MeV energy range in conjunction with the underlying reaction dynamics in the scarcely explored light-medium mass region. The stack foil activation technique followed by offline gamma; spectroscopy was employed to measure the cross sections of residues populated in the reaction. The measured data were compared with theoretical predictions from statistical model codes like PACE4 and EMPIRE3.2.2 to probe the underlying reaction dynamics. The imitation of n- and p-channel data grossly by both the model codes suggests the production of residues via the complete fusion (CF) mode, while the enhancement observation in alpha;-channel cross sections hints at the signatures of breakup fusion in addition to the dominant CF. We report a new branching intensity of 93.31 keV gamma; -line retrieved experimentally from 67Ga decay following the end of bombardment activity in each target foil. The optimized production of 67Ga is also reported from the application perspective.
