Charge transfer reactions of 3He in carbon at 68, 99 and 130 MeV

Abstract Fractions of equilibrium singly charged 3 He 1+ ions produced by 3 He 2+ beams going through carbon targets were measured at 68, 99 and 130 MeV incident energies. The thickness dependence of the 3 He 1+ / 3 He 2+ fraction was measured, which allowed to deduce the electron capture cross section. The experimental results are compared with the first and higher order Born approximation theories.
