Experiments are described in which neutrons produced by mu - capture in Pb were detected by paraffin recoil protons causing fluorescence in ZnS(Ag). The experimental set-up is described. The data show that most of the neutrons have energies below-3 Mev. Since the neutrons, according to their point of origin, have traveled great distances in the mu -meson absorber and have been left as lower-energy neutrons on the basis of their energy loss through inelastic scattering in the Pb, the total intensity of recoil protons is very small, though 25 captures/minute were recorded. An even larger recoil-proton count rate would be expected if neutrons with energies greater than 25 Mev were selected. (T.R.H.)
