| 摘 要： | We study a non-stationary electronic wave packet in a quantized electromagnetic field.Generally,the electron and field become entangled as the electronic wave packet evolves.Here we find that,when the initial photon state is a coherent one,the wavefunction of the system can be factorized if we neglect the transferred photon number.In this case,the quantized-field calculation is equivalent to the semi-classical calculation.
