Ionization and charge transfer in proton-helium collisions. (1991)
Journal Article
Slim, H., Heck, E., Bransden, B., & Flower, D. (1991). Ionization and charge transfer in proton-helium collisions. Journal of Physics B: Atomic, Molecular and Optical Physics, 24(17), L421-L424. https://doi.org/10.1088/0953-4075/24/17/002

Cross sections have been calculated for single ionization in collisions between protons and helium atoms, in the range of projectile energies 25-100 keV. The semiclassical impact parameter method was employed, with a basis comprising 22 states on the... Read More about Ionization and charge transfer in proton-helium collisions..

Theoretical differential cross sections for proton-helium scattering at intermediate energies. (1991)
Journal Article
Slim, H., Heck, E., Bransden, B., & Flower, D. (1991). Theoretical differential cross sections for proton-helium scattering at intermediate energies. Journal of Physics B: Atomic, Molecular and Optical Physics, 24(9), 2353-2358. https://doi.org/10.1088/0953-4075/24/9/014

Differential cross sections for collisions between protons and helium atoms have been calculated in the range of impact energies from 25-100 keV. The eikonal formula for the differential cross section was used, in conjunction with semiclassical trans...

Charge transfer and excitation in proton-helium collisions. (1991)
Journal Article
Slim, H., Heck, E., Bransden, B., & Flower, D. (1991). Charge transfer and excitation in proton-helium collisions. Journal of Physics B: Atomic, Molecular and Optical Physics, 24(7), 1683-1694. https://doi.org/10.1088/0953-4075/24/7/021

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... Read More about Charge transfer and excitation in proton-helium collisions..
