Abstract

Energy and angular correlations between α particles and quasielastic projectilelike fragments produced in the Ne20 + Au197 reaction at 290 MeV show that the α particles are sequentially emitted from long-living states of primary fragments populated in direct reactions such as inelastic scattering and few-nucleon transfer. An analysis of the energy-integrated angular correlation leaves no notable cross section for a direct breakup or uncorrelated particle emission.

NUCLEAR REACTIONS Ne20 + Au197, ENe=290 MeV, measured energy and angular correlations of α particles in coincidence with N15, O16. Deduced reaction mechanism of quasielastic projectile dissociation.
