Abstract
Irradiation with 100 Mev x-rays has been found to produce from copper and from aluminum. Experiments involving variations in beam energy and target thickness have shown that these isotopes result from secondary reactions caused by photo-neutrons and photo-protons from the target materials rather than from any primary, x-ray induced processes. No evidence for gamma-meson reactions has been obtained. A search for the transmutation products of gamma-meson reactions is shown to compare favorably in sensitivity with cloud-chamber methods for the detection of meson production, provided mesons are produced singly.
