论文摘要
在外部磁场或电场的影响下，考虑了$^{2}π_{3/2} $基态的LIO分子的超电碰撞。在存在适度的实验室强度磁场和电场的情况下，非弹性碰撞被抑制。 弹性碰撞的速率使热分布重新分布，以及相应的较低加热状态变化碰撞的速率，表明可以达到量子退化或什至分子bose-enstein凝结，前提是可以达到Millikelvin的初始温度。
Ultracold collisions of LiO molecules in the $^{2}Π_{3/2}$ 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.
