摘要：
The motion of a two-dimensional Gaussian wave packet was analyzed under crossed electric and magnetic fields by solving the time-dependent Schrodinger equation numerically. It was found that the perpendicular magnetic field prevents the expansion of the wave packet and the in-plane electric field transfers the wave packet. The possibility of trapping and transfer of the wave packet is discussed by introducing a phenomenological decay term into the partial waves.
