Abstract
An experiment to measure the effective mass of positrons in metals is discussed. We take advantage of the fact that there is a sharp break in the angular-correlation curve of the annihilation rays at the Fermi momentum. The experiment then consists in a study of the temperature dependence of the angular-correlation curve, to find how this break disappears with rise of temperature.
