# Bremsstrahlung cross section for a point, spinless target

## Description

Abstract A program is described which calculates the double differential cross section for bremsstrahlung production by electrons interacting with a spinless point target. The cross section, which includes recoil of the target particle, is valid at relativistic energies and wide angles. Title of program: BREMPNT Catalogue Id: ABRV_v1_0 Nature of problem The differential cross section for bremsstrahlung was originally calculated by Bethe and Heitler. The Bethe-Heitler cross section has a complicated form which, thus far, has required the use of either numerical methods to integrate the differential cross section or severe approximations for analytic integration. In addition, as discussed by Maximon, de Miniac and Aniel, the direct use of the Bethe-Heitler cross- section is complicated by a sharp structure which can lead to the loss of 10 or more ...
