Inclusive spectra have been measured for neutrons emitted from nuclei bombarded by ..pi../sup -/ mesons with momentum 3 GeV/c. The secondary neutrons were detected in the interval of kinetic energies 25 < or approx. = T/sub n/ < or approx. = 160 MeV. Measurements were made on the nuclei C, Cu, Pb, and U in the angular range from 60 to 160/sup 0/ with 10/sup 0/ steps. At angles 90, 120, and 160/sup 0/ measurements were made for 12 nuclei from Be to U. It was found that the dependence of the neutron yield on the number of neutrons in the nucleus is similar to the dependence of the proton yield on the number of protons in the nucleus, but even for the isospin-symmetric carbon nucleus under the experimental conditions the yield of neutrons is greater than the yield of protons.
