Abstract

The average multiplicity

〈 ν 〉

of neutrons emitted from a nucleus which has absorbed a

μ^{-}

meson has been determined for several materials:

〈 ν 〉 = 2.14 \pm 0.13

for Pb, 2.32±0.17 for Bi, 1.54±0.12 for Sn, 0.95±0.17 for Al. From

〈 ν 〉

, by using compound nucleus theory, the average excitation given the nucleus was found to be about 20 Mev for all the nuclei studied.
