The reduction of the coherence area of high-energy electrons in the passage through a crystal

Уменьшение когерентной области для электронов высокой энергии при прохождении через кристалл

Summary

In this paper we investigate how the coherence area of an high-energy electron is reduced in the passage through a crystal. This problem was suggested by an investigation of photo-Coulomb interference arising from coherent bremsstrahlung. The answer is that the coherence area is reduced to atomic dimensions after a path of a few microns only.

Riassunto

Nell’investigare un fenomeno di interferenza fotocoulombiana è risultato importante determinare come si riduce l’area di coerenza nel passaggio di elettroni di alta energia attraverso cristalli. Nel presente lavoro è affrontato questo problema e si giunge alla conclusione che dopo pochi micron di percorso l’area di coerenza ha dimensioni non superiori a quelle atomiche.

Резюме

В этой работе исследу ется вопрос о сокращении Когерент ной области для электронов высок ой энергии при прохож дении через кристалл. Эта проблем а возникает при рассм отрении явления фото-куЛоновской интерфе ренции, которая явления фото-куЛонов ской интерференции, к оторая имеет место при Когер ентном тормозном изл учении. Получен важный резул ьтат, что Когерентная обла сть сокращается до ат омных размеров после прохо ждения нескольких ми крон.
