从实验和理论两方面研究了磁光陷阱(MOT)冷却光对俘获的Rb2+(Rb)分子离子的直接光解。在Rb MOT中，光缔合形成的Rb{2}分子通过光致电离产生振动激发的Rb{2}^{+}离子，并被捕获在改进的球形Paul陷阱中。测量了在MOT冷却光作用下俘获的Rb2+离子信号的衰减率，并与我们计算的分子离子光解速率一致。由于MOT光的光解离机制被认为是活跃的，因此对所有同核双原子碱金属分子离子都是普遍的。
The direct photodissociation of trapped ^{85}Rb_{2}^{+} (rubidium) molecular ions by the cooling light for the ^{85}Rb magneto-optical trap (MOT) is studied, both experimentally and theoretically. Vibrationally excited Rb_{2}^{+} ions are created by photoionization of Rb_{2} molecules formed photoassociatively in the Rb MOT and are trapped in a modified spherical Paul trap. The decay rate of the trapped Rb_{2}^{+} ion signal in the presence of the MOT cooling light is measured and agreement with our calculated rates for molecular ion photodissociation is observed. The photodissociation mechanism due to the MOT light is expected to be active and therefore universal for all homonuclear diatomic alkali metal molecular ions.
