Dp. Higgins et al., CROSS-SECTIONS FOR H(2P) FORMATION IN SLOW HE2-H COLLISIONS(), Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 103(2), 1995, pp. 120-122
A crossed beam method has been used to obtain cross sections for 2p ex
citation of H by 4-9 keV amu(-1) He2+ ions. The measurements complemen
t our previous higher energy measurements and provide a useful assessm
ent of a number of greatly different theoretical predictions. In parti
cular the measurements confirm a strong undulatory dependence on energ
y predicted by recent close coupling calculations.
