Abstract
The radioactivity produced in copper and carbon strips by irradiation with 66 Mev bremmstrahlung is used to determine the angular spread of the X-ray beam. The beam breadth at half maximum intensity indicated an angular spread of 2.03 +/- 0.03 degrees with copper, and a spread of 2.08 +/- 0.04 degrees with carbon detectors. These results are approximately eight per cent smaller than predicted by Schiff's theory for a target of tungsten, 5 mils thick.
