摘要：

A study has been made of the production of evaporation neutrons in the interaction of high-energy muons with lead nuclei. The detected neutrons arise from the direct electromagnetic interaction of the fast muons with lead nuclei and the interaction of photons from cascades initiated by knock-on electrons. Information about the total photonuclear cross section at high energies can be obtained from this muon interaction experiment by considering the virtual photon spectrum of the muons. The measured value of the product of the cross section per lead atom and mean multiplicity corresponds to those calculated on the Kessler theory under the assumption of a constant photonuclear cross section above 1 GeV. The experimental results disagree with the assumptions made by Hodgson and Jameel who predict a decrease of the total photonuclear cross section at high energies. © 1968.
