چکیده
We predict the presence and positions of purely-long-range bound states of He(2s S)1He(2p P) near the 2s S112p P0,1 atomic limits. The results of the full multichannel and approximate models are compared, and we assess the sensitivity of the bound states to atomic parameters characterizing the potentials. Photoassociation to these purely-long-range molecular bound states may improve the knowledge of the scattering length associated with the collisions of two ultracold spin-polarized He(2s S) atoms, which is important for the studies of Bose-Einstein condensates.

The bound states of the fermionic (3)He(2 (3)S(1)) + (3)He(2 (3)P(j)) system, where j = 0, 1, 2, are investigated using the recently available ab initio short-range (1,3,5)Σ(+)(g,u) and (1,3,5)Π(g,u) potentials computed by Deguilhem et al. (J. Phys. B: At., Mol. Opt. Phys., 2009, 42, 015102). Single-channel and multichannel calculations have been undertaken in order to investigate the effects o...
متن کاملLong-range interactions of excited He atoms with the alkaline earth atoms Mg, Ca, and Sr.
Dispersion coefficients for the long-range interactions of the first four excited states of He, i.e., He(2 (1, 3)S) and He(2 (1, 3)P), with the low-lying states of the alkaline earth atoms Mg, Ca, and Sr are calculated by summing over the reduced matrix elements of multipole transition operators.

Long-range potentials have been calculated for He2 molecules dissociating to He 2 S + He 2 P, including the retarded dipole and the van der Waals interactions. Ultra-long-range wells with depths of up to about 2.4 GHz have been found in many of the adiabatic body-fixed potentials and rovibrational levels have been calculated for some of these wells, which have been found to support up to 4 rota...
