Abstract

We predict the presence and positions of purely-long-range bound states of 4He(2s 3S)+4He(2p 3P) near the 2s 3S1+2p 3P0,1 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 4He(2s 3S) atoms, which is important for the studies of Bose-Einstein condensates.
