AHARONOV-BOHM OSCILLATIONS IN A HYDROGEN-ATOM IN A RADIATION-FIELD THROUGH ELECTRON SELF-INTERFERENCE

We study the influence of a weak magnetic field on time evolution of a quantum state that is a coherent superposition of two counter-rotatin g Trojan wave packets in a linearly polarized electromagnetic field. W e demonstrate that both the interference pattern of the electron proba bility density and differential cross section for half-cycle pulse ion ization exhibit periodic modulation as a function of magnetic flux cut ting the plane of packet motion. The shift is proportional to the magn etic flux in a way characteristic for the Aharonov-Bohm effect. [S1050 -2947(98)06202-7].
