From measurements of coincidences of pulses from fission fragments and neutrons accompanying spontaneous fission of /sup 238/U, we have determined the probability P/sub ..nu../ of emission of various numbers of neutrons and certain other statistical characteristics of the distribution of neutrons in multiplicity. The measurements were made in a neutron detector with /sup 3/He counters with a neutron-detection efficiency from 0.21 to 0.38. The following values were obtained: P/sub 0/=0.052, P/sub 1/=0.277, P/sub 2/=0.366, P/sub 3/=0.247, P/sub 4/=0.050, P/sub 5/=0.008, nu-bar=199, GAMMA/sub 2/=0.75, and sigma/sub ..nu..//sup 2/=1.00.
