Query: Temperature dependence of slow positron reemission from metals   Intensity of positron reemission from a metal is related to its work
function. This property is dependent on temperature and can be modified with
temperature control. In this article a simple model is proposed to explain and
predict the variation of the positron work function with temperature. The
dependence of slow positron yield of metals on temperature is predicted based
on this model and the critical temperatures at which the slow positron yield is
maximum is calculated. The proposed model is consistent with experimental
observations.
