将不同共振频率多原子系统集体自发辐射的量子理论用于讨论两个独立跃迁的两组原于的超辐射。在旋波近似、缓变包络近似及退关联近似下得到了辐射强度随时间变化的解析表达式。

A quantum theory for collective spontaneous emission of a multiatomic system with different resonance frequencies is, applied here to the superradiant emission of two groups of atoms undergoing two independent transitions. An analytical expression for the emmited intensity as a function of time is obtained after making rotating wave approximation, slowly varying envelope approximation and decorrelation approximation.
