摘要：We investigate theoretically the photoassociation process of Rb-85 atoms driven by a short laser pulse at several millikelvins. At this temperature, the actions of the rotational barrier, weights of initial scattering states, and shape resonance emerge and have an influence on the thermally averaged photoassociation probability. The calculated thermal weighted population distribution of rotational states agrees well with photoassociation spectrum experiment. The thermally averaged photoassociation probability decreases with an increase in temperature.
