Summary

Bethe-Heitler cross-sections for electron bremsstrahlung and pair production in the field of a target particle of arbitrary spin are obtained, including recoil effects. Formulae for extreme relativistic energies are obtained as special cases. A formula for symmetric pair production, valid for all energies and emission angles, is given. Inelastic target processes are included in a straightforward manner.

Riassunto

Le sezioni d’urto di Bethe-Heitler per la bremsstrahlung degli elettroni e la produzione di coppie nel campo di una particella bersaglio di spin arbitrario si ottengono comprendendo gli effetti di rinculo. Si ottengono, come casi speciali, formule per le energie relativistiche estreme. Si dà una formula per la produzione simmetrica di coppie, valida a tutte le energie ed a tutti gli angoli di emissione. Si includono in modo diretto i processi inelastici del bersaglio.

Реэюме

Вычисляются поперечные сечения Бете-Гайтлера для тормоэного иэлучения злектронов и рождения пар в поле частицы мищени, с учетом зффектов отдачи. Как частный случай, получаются формулы для ультрарелятиви стских знергий. Приводится формула для симметричного рождения пар, справедливая для всех знергий и углов испускания. Неупругие процессы в мищени учитываются непосредственным обраэом.
