Elastic Scattering of 6He based on a Cluster Description
Abstract
Elastic scattering observables (differential cross section and analyzing power) are calculated for the reaction 6He(p,p)6He at projectile energies starting at 71 MeV/nucleon. The optical potential needed to describe the reaction is derived describing 6He in terms of a 4He-core and two neutrons. The Watson first order multiple scattering ansatz is extended to accommodate the internal dynamics of a composite cluster model for the 6He nucleus scattering from a nucleon projectile. The calculations are compared with the recent experiments at the projectile energy of 71 MeV/nucleon. In addition, differential cross sections and analyzing powers are calculated at selected higher energies.
