Ultracold collisions of the lithium monoxide radical

Abstract

Ultracold collisions of LiO molecules in the ${}^2{\Pi }_{3/2}$ ground state are considered, under the influence of either an external magnetic or electric field. Inelastic collisions are shown to be suppressed in the presence of modest laboratory strength magnetic and electric fields. The rate of elastic collisions that rethermalize the thermal distribution, and the corresponding low rate of heating state-changing collisions, suggest that quantum degeneracy or even molecular Bose-Einstein condensation of LiO gas may be attainable, provided that the initial temperatures in the milliKelvin range are achievable.
