摘要：

We describe how a quasibound state that is in Feshbach resonance with an incoming atom wave and is coupled to a nondecaying bound state by an electromagnetic field will exhibit a quantum interference that controls the collision dynamics. By varying the frequency of a coupling field, the elastic cross section may be modulated. By varying the amplitude of a coupling field, the bound diatomic population may be increased by several orders of magnitude.
