Title

He2+ on He: State-Selective, Scattering-Angle-Dependent Capture Cross Sections Measured by Cold Target Recoil Ion Momentum Spectroscopy (COLTRIMS)

Abstract

We present the first state-selective, scattering-angle-dependent cross sections for the reaction 0.25-1 MeV He2+ + He → He1+ + He1+. The experiment was performed, using a new generation of recoil ion momentum spectroscopy, which enabled us to determine the three momentum components and the charge state of the recoil ion simultaneously. An absolute momentum resolution of ±0.13 a.u. for the longitudinal and ±0.02 a.u. for the transverse momentum component has been achieved, which is equivalent to a resolution in projectile energy loss of ±5.6 eV and an uncertainty of the projectile scattering angle of better than ±1 μrad.
