Abstract

Experimental studies have been made of superelastic and inelastic collision processes involved in the state-selective single-electron capture reaction ³He²⁺+He(1 ¹S)→ ⁺He+(n)+He+(n’), where n and n’ are the final principal quantum-number states of the collision products. Total cross sections have been measured at projectile energies of 15, 30, and 45 keV/u, by examining the energy loss-gain of the fast ³He⁺ product ions, for the superelastic n=n’=1 channel, and for the sum of the inelastic n=2, n’=1 and n=1, n’=2 states. Measurements are also presented for Ne and Ar targets.
