In this work alpha induced reaction on cobalt(59Co) in the energy range of 10 to 80 Mevrnhave been demonstrated. Excitation function for three reactions of the type 59Co( ; n)62Cu,rn59Co( ; 2n)61Cu, 59Co( ; 3n)60Cu were studied. For theoretical excitation function com-rnputer code COMPLET have been used. High energy parts of the excitation functionsrnare dominated by pre-equilibrium reaction mechanism where as the low energy parts arerndominated by compound nucleus reaction mechanism with its characteristic peak
