| Abstract: | The time required for the thermalization of positrons in ionic crystals is estimated. It is shown that the proton-thermalization time in an ionic crystal is much shorter than the shortest positron lifetime with respect to annihilation, so positron annihilation can be used to study the energy spectrum of valence electrons in ionic crystals.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 4, pp. 68–72, April, 1971. |
