Abstract
We use a variational perturbative method for the calculation of the en ergy levels of impurity magnetopolarons in parabolic quantum wires. Th e method is reasonable for all electron-phonon coupling alpha, all Ryd berg constant R, all parabolic frequency omega and all cyclotron frequ ency omega(c). The ground state and first excited state energies are c omputed by the method and their dependence on alpha, R, omega and omeg a(c) is discussed.
