Photodissociation and radiative association of HeH+ in the metastable triplet state
J. Loreau, S. Vranckx, M. Desouter-Lecomte +2
We investigate the photodissociation of the metastable triplet state of HeH+ as well as its formation through the inverse process, radiative association. In models of astrophysical…
A fundamental limit to the efficiency of spin-exchange optical pumping of 3He nuclei
T. V. Tscherbul, P. Zhang, H. R. Sadeghpour +1
We establish the existence of a fundamental limit to the efficiency of spin-exchange optical pumping of 3He nuclei by collisions with spin-polarized alkali-metal atoms. Using accur…
Sympathetic cooling of polyatomic molecules with S-state atoms in a magnetic trap
T. V. Tscherbul, H-G. Yu, A. Dalgarno
We present a rigorous theoretical study of low-temperature collisions of polyatomic molecular radicals with ^1S_0 atoms in the presence of an external magnetic field. Accurate quan…
Collisional properties of cold spin-polarized nitrogen gas: theory, experiment, and prospects as a sympathetic coolant for trapped atoms and molecules
T. V. Tscherbul, J. Klos, A. Dalgarno +6
We report a combined experimental and theoretical study of collision-induced dipolar relaxation in a cold spin-polarized gas of atomic nitrogen (N). We use buffer gas cooling to cr…
RF-field-induced Feshbach resonances
T. V. Tscherbul, T. Calarco, I. Lesanovsky +3
A rigorous quantum theory of atomic collisions in the presence of radio frequency (rf) magnetic fields is developed and applied to elucidate the effects of combined dc and rf magne…
Charge Transfer Between Neutral Atoms and Highly Ionized Species: Implications for ISO Observations
G. J. Ferland, K. T. Korista, D. A. Verner +1
We estimate rate coefficients for charge transfer between neutral hydrogen and helium and moderate to highly ionized heavy elements. Although charge transfer does not have much inf…
