摘要：
Dynamical processes in quantum system are studied on the basis of Coleman-IIepp model. We present a theoretical framework using a spin coherent stale representation. This enables us to obtain averages and quasi-probability densities which give derailed information on the dynamics of a detector as well as an incident particle. Numerical calculations are also done.
