摘要：
We study the resonant magnetopolaron effects in parabolic quantum wells in a tilted magnetic field. The renormalization of the first excited level, which is resonant with the ground state level plus one longitudinal-optical phonon is calculated at the resonance using an improved resonance approximation to be DELTAE=gammaalpha(beta) where alpha is the polaron coupling constant. The exponent beta and the factor gamma are calculated in dependence on the tilt angle of the magnetic field and the confinement energy.
