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…
Few-neutron systems with the long-range Casimir-Polder force
R. Higa, J. F. Babb
In this work we present results of the long-range electromagnetic Casimir-Polder interactions between two neutrons, a neutron and a conducting wall, and a neutron between two walls…
Revisiting the Formation of HeH in the Planetary Nebula NGC 7027
R. C. Forrey, J. F. Babb, E. D. S. Courtney +2
From four independent calculations using three different theoretical approaches, rate coefficients for the formation of HeH via the radiative association of He and H were c…
Radiative association of atomic and ionic carbon
James F. Babb, R. T. Smyth, B. M. McLaughlin
We present calculated cross sections and rate coefficients for the formation of the dicarbon cation (C) by the radiative association process in collisions of a C atom…
