Excitation functions for the 5'V[a, n). (a, 3"). (a, p3n). (a. p6nL (a, 03n). (e. a2pn). (e, 201). (a. 2nn) and (a. 2013n)l 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 wirh poor resolution scintillation and Ge(Li) detectors some 20 years ago. The reaction V(e. p6n) is measured for the first time, The experimenlal results are compared with calculations considering equilibrium as well as pre-equilibrium reactions according to the hybrid model of Blann. A broad general agreement is observed between the experimental results and theorerical Predictions with M initial exciton configunfion of no = (4pOh).

Reaction product cross sections have been measured for reactions of 4He projectile with 54'5617e, 58Ni and 59C0 targets in the bombarding energy range 14-27 MeV. The cross-section-weighted average charge A Z and mass AA removed from the compound system were deduced and compared with results reported for heavy-ion induced reactions. Variation ofA A with E* N is independent of the initial angular momentum of compound nucleus in the A = 60 mass region in contrary to the rare-earth region. This would suggest a strong angular momentum removal from the compound nucleus by evaporation of particles for A ,~ 60 nuclei. The average evaporated charge AZ depends on both the CN excitation energy E~N and the compound nucleus N and Z numbers. The AA and AZ dependence on excitation energy and the projectile-target combination can be understood in terms of the statistical model calculations.
