Abstract

In this work we calculated the wave function, the binding energy and the lifetimes for self and pickoff annihilation channels of o-Ps placed in a one dimensional Bloch-potential. The periodicity and the amplitude of the potential were varied in wide ranges to simulate different physical and chemical conditions. We applied non-relativistic approximation and the actual wave function of o-Ps was constructed by the help of perturbation theory using the first twenty unperturbed S-states of positronium.
