Abstract

A theory of positron annihilation in Cooper-pair superconductors is presented. It is assumed that the positron and electrons are not correlated. It is argued that a comparison of positron data with density-of-states measurements might be used to test the hypothesis that superconductivity in the high-temperature superconductors results from pair formation. The prospects for the observation of the effects of the superconductive transition are briefly reviewed.
