Excitation functions of alpha particle induced reactions in cobalt in the energy range 10-120 MeV using variable energy cyclotrons
Alpha particle induced reactions on the target element cobalt were investigated from 10 to 120 MeV, using foil stack activation technique and the Ge(Li) gamma ray spectroscopy method. Ten excitation functions for reaction residues 51Cr, 52,54Mn, 56,57Ni, 59Fe and 56,57,58,60Co were measured, of which 59Co(α, p6n) 56Ni reaction was measured for the first time. A comparison with pre-equilibrium hybrid model was made using initial exciton number, n0 = 4 (4pOh). It is observed that for ( α, xn ypz α) type reactions the agreement is within a factor of 2, while for ( α, xn yp) type the disagreement is generally by more than an order of magnitude.
