Fine-structure transitions of Si and S induced by collisions with atomic hydrogen

Pei-Gen Yan, James F. Babb

Using a quantum-mechanical close-coupling method, we calculate cross sections for fine structure excitation and relaxation of Si and S atoms in collisions with atomic hydrogen. Rat…

Fine-structure transitions of the carbon isoelectronic sequence C, N and O induced by collisions with atomic hydrogen

Pei-Gen Yan, James F. Babb

Fine-structure transitions can be involved in various processes including photon absorption, charge transfer and inelastic collision between ions, electrons and neutral atoms. We p…

Long-range additive and nonadditive potentials in a hybrid system: Ground state atom, excited state atom, and ion

Pei-Gen Yan, Li-Yan Tang, Zong-Chao Yan +1

We report a theoretical study on the long-range additive and nonadditive potentials for a three-body hybrid atom-atom-ion system composed of one ground state Li atom, one excit…

Photoionization of Rb ions in the valence energy region 37 eV -- 44 eV

Brendan M McLaughlin, James F Babb

Absolute photoionization cross sections for the Rb ion were recently measured at high resolution over the energy range 37.31 eV -- 44.08~eV, with autoionizing Rydberg resona…
