英文摘要：

By using an analytical method, exact solutions of the equation for a single tapped electron adiabatically interacting with an external field is obtained. Such exact solutions describe a series of exact squeezed coherent states of this quantum system, whose configuration of probability density is breathing and oscillatory wave-packets. The time evolutions of the expectation of coordinate, momentum and energy are greatly affected by the adiabatic factor in a time interval. Therefore, manipulation of quantum state can be realized by suitably adjusting adiabatic parameters.
