Abstract

We use the coherent-state path integral and an angular model for the spin to solve the pseudo-hermitian interaction between an oscillator and a spin-1/2 particle in an external magnetic field. The propagators are given explicitly as a perturbation series and are summed up exactly. The energy spectrum and the bi-orthonormal basis of states are deduced.
