Ultracold homonuclear and heteronuclear collisions in metastable helium
D. G. Cocks, I. B. Whittingham, G. Peach
Scattering and ionizing cross sections and rates are calculated for ultracold collisions between metastable helium atoms using a fully quantum-mechanical close-coupled formalism. H…
Collision processes: Division B / Commission 14 / Working Group Collision processes
Gillian Peach, Milan S. Dimitrijevic, Paul S. Barklem
This report summarizes new publications on the results of research in atomic and molecular collision processes and spectral line broadening.
Effects of non-adiabatic and Coriolis couplings on the bound states of He(2 ^3S)+He(2 ^3P)
Daniel G Cocks, Ian B Whittingham, Gillian Peach
The effects of non-adiabatic and Coriolis couplings on the bound states of the He(2 ^3S_1)+He(2 ^3P_j) system, where j=0,1,2, are investigated using the recently available ab initi…
Autoionization of spin-polarized metastable helium in tight anisotropic harmonic traps
Timothy J. Beams, Ian B. Whittingham, Gillian Peach
Spin-dipole mediated interactions between tightly confined metastable helium atoms couple the spin-polarized quintet state to the singlet state…
Collisional broadening of alkali doublets by helium perturbers
D. F. T. Mullamphy, G. Peach, V. Venturi +2
We report results for the Lorentzian profiles of the Li I, Na I and K I doublets and the Na I subordinate doublet broadened by helium perturbers for temperatures up to 3000 K They…
Spin-dipole induced lifetime of the least-bound quintet sigma state of He(2S)+He(2S)
Timothy J. Beams, Gillian Peach, Ian B. Whittingham
The properties of the least-bound vibrational level (v=14) of the quintet sigma state formed during the ultracold collision of two spin-polarized metastable helium atoms are crucia…
