Distorted-wave impulse-approximation calculations for quasifree cluster knockout reactions

Abstract

A formalism for distorted-wave impulse-approximation calculations of quasifree cluster knockout reactions is described. Results are presented for ($p, p\ensuremath{\alpha}$) and ($\ensuremath{\alpha}, 2\ensuremath{\alpha}$) reactions. In both cases distortion effects are large. It is concluded that incident energies between \ensuremath{\sim} 100 and \ensuremath{\sim} 200 MeV are most suitable for ($p, p\ensuremath{\alpha}$) studies of nuclear structure, whereas somewhat higher energies are more appropriate for ($\ensuremath{\alpha}, 2\ensuremath{\alpha}$) studies.NUCLEAR REACTIONS DWIA reaction theory of cluster knockout.
