Nuclear Size Effect on Bremsstrahlung in the BeV Range

Abstract

Since a more detailed knowledge of the bremsstrahlung cross section at high energies may be required for certain photoproduction experiments, the percentage correction to the Bethe-Heitler point-nucleus results arising from the finite size of the nuclear-charge distribution is estimated. The effect of a shape-independent approximation to the form factor is considered. The results presented in Table I of the text indicate corrections of less than a few percent for incident electrons with energies in the BeV range. A comparison with previous work is also made.
