Abstract
Measurements were made of the neutron yields from a lead absorber 60 c m thick in electromagnetic cascades initiated by 200-600 MeV electrons . A comparison between the neutron yields obtained for electrons and t he results of similar measurements for protons and pions suggests that the rejection factor of the proton background is increased similar to 10(2) times when an ionization-neutron calorimeter is used to measure primary cosmic radiation electrons at energies above 100 GeV.
