Direct α particle emission in incomplete fusion reaction on a spherical target124Sn

Abstract

Direct α particles cross sections and angular distributions have been measured when bombarding a124Sn target with various projectiles:16O (90, 105, 125 MeV)19F (104 MeV)20Ne (112, 156 MeV). Results have been found independant of the projectile structure. In the same reactions, gamma multiplicity measurements have shown that direct α particles are emitted in collisions with intermediate impact parameters. The angular momentum is found to be about half of the valuel cr for complete fusion.
