Particle removal reactions with deformed projectiles

Abstract

Single-particle removal reactions are becoming an important tool for studying radioactive nuclei. The nuclei far from stability may reveal new regions of large deformation. We discuss the influence of the projectile deformation on the stripping cross sections and longitudinal momentum distributions of the core. The Glauber formalism for describing such reactions is developed and compared with the simpler geometric approach and with existing experimental data. The most significant effects are expected for nuclei with valence spherical orbitals strongly mixed by deformation. The shape of the momentum distribution, in turn, can be used for determining the degree of deformation of the projectile.
