Abstract: | The equation is formulated and accurately solved for the problem of the transport of photoexcited electrons which undergo scattering before reaching vacuum, with the formation of an electron-hole pair, as well as multiple scattering of elastic type. The analytical expressions obtained permit calculations of the spectral composition of the emitted-electron flux and the quantum yield of photoemission. The limiting expression for the probability that secondary electrons will reach the vacuum which is obtained when the elastic-scattering mechanism is switched off is compared with literature data.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 10, pp. 86–92, October, 1987. |
