Effects of pre-equilibrium nucleon emission on excitation functions of various reactions in vanadium induced by alpha particles

Abstract

Excitation functions for the 51V(( alpha ,n), ( alpha ,3n), ( alpha ,p3n), ( alpha ,p6n), ( alpha , alpha 3n), ( alpha , alpha 2pn), ( alpha ,2 alpha ), ( alpha ,2 alpha n) and ( alpha ,2 alpha 3n)) reactions have been measured up to 120 MeV using the stacked foil technique with a view to improving the quality of data, which were measured with poor resolution scintillation and Ge(Li) detectors some 20 years ago. The reaction V( alpha ,p6n) is measured for the first time. The experimental results are compared with calculations considering equilibrium as well as pre-equilibrium reactions according to the hybrid model of Blann(1984). A broad general agreement is observed between the experimental results and theoretical predictions with an initial exciton configuration of n0=(4p0h).
