We use the coherent state path integral and a fermion model for the spin to solve a non-linear bosonic generalization of the Jaynes-Cummings model. The propagators are given explicitly as perturbation series. These are summed up exactly for special cases and the corresponding atomic population inversion as well as energy spectrum and wave functions are deduced.
