| Description | Journal: Journal of Physics B: Atomic, Molecular and Optical Physics Using the semiclassical impact parameter method, the authors have computed cross sections for excitation of He by $H^{+}$ and for one-electron charge transfer, the collision energy being in the range from 10-235 keV. A basis of travelling atomic orbitals was used, comprising 11 states on the helium target and 29 states on the projectile. Results are presented both including and neglecting the effects of two-electron exchange arising from the Pauli exclusion principle. Comparison is made with measurements of the density matrix elements relating to capture into the n=2 and n=3 states of hydrogen and with measurements of the cross sections for excitation of the 1s2s$ ^{1}$ S and 1s2p$ ^{1}$ P levels of helium. Comparison is also made with relevant calculations, including recent computations based upon a one-electron model. |
