Abstract

Simple models of continuous superselection rules with transparent physical interpretation are used to indicate that (1) a continuous super-selection rule can give rise to reduction of wave packets in quantum mechanical separation procedure (in contrast to measuring procedure) in the infinite time limit and (2) a continuous superselection rule arises when the limit of an infinite mass of a scattering center is taken. The latter is used to illustrate the Machida-Namiki model of quantum mechanical measurement. Some no-go theorems are shown.
