| Summary: | The different causes that lead to polarisation effects in heavy-ion scattering are analysed. In semi-classical theories of heavy-ion reactions in which the relative motion is treated classically and the internal excitation by quantum mechanics there are no polarisation effects in the scattering if there is no absorption or inelastic scattering during the collision. A consistent quantum-mechanical treatment of both the relative motion and internal degrees of freedom is necessary to allow for the influence of the polarisation of the projectile on its relative motion with the target. In this paper the path integral method is used to calculate polarisation effects in heavy-ion reactions. It is shown that corrections to the primitive semi-classical propagator must be included to calculate the leading-order polarisation effects. Expressions for the analysing power are obtained. A simple model hamiltonian is used to illustrate the procedure. © 1993. |
