Ionization, excitation, and electron transfer in MeV-energy collisions between light nuclei andC5+(1s)ions studied with a Sturmian basis

Abstract

Cross sections have been determined for direct excitation, ionization, and electron transfer in collisions between H, He, Li, and Be nuclei and ${\mathrm{C}}^{5+}(1s)$ target ions at nuclear energies $1--24$ MeV/nucleon, extending earlier work [Phys. Rev. A 56, 2903 (1997)] to higher energies. Coupled Sturmian pseudostates of principal quantum number at least up to 30 have been included for each angular momentum $s$, $p$, $d$, and $f$ centered on the C nucleus, as well as a $1s$ state centered on the projectile. Detailed basis-convergence studies have been carried out. Cross sections have been compared with the corresponding Born results, and scaling rules have also been examined.
