Abstract
Angular distributions of alpha-particles emitted from magnesium+magnesium reactions are calculated at different incident energies. The alpha-particles are sequentially emitted from long-lived states of primary fragments populated in direct reactions. The present reaction yields to multifragmentation with the result of twelve alpha-particles which are dealt with using the cluster model. The statistical scission model is used in developing the angular distributions of the fragments. The angular distributions and variances of this multifragmentation process have been numerically calculated. The obtained results are in good agreement with previous calculations.
