Quasi-molecular electron promotion beyond the 1s$\sigma$ and 2p$\pi$ channels in slow collisions of He${}^{2+}$ and He

L. Ph. H. Schmidt, M. S. Schöffler, C. Goihl +3

The electron emission pattern of transfer-ionization in collisions of He${}^{2+}$ with He was investigated for impact velocities between 0.53 a.u. and 0.77 a.u. (7 keV/u - 15 keV/u)…
