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…
Photoassociation spectra and the validity of the dipole approximation for weakly bound dimers
Daniel G. Cocks, Ian B. Whittingham
Photoassociation (PA) of ultracold metastable helium to the 2s2p manifold is theoretically investigated using a non-perturbative close-coupled treatment in which the laser coupling…
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…
Laser Intensity Dependence of Photoassociation in Ultracold Metastable Helium
Daniel G Cocks, Ian B Whittingham
Photoassociation of spin-polarized metastable helium to the three lowest rovibrational levels of the J=1, state asymptoting to 2SP is studie…
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…
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…
