Neutron spectra from (p,n) reactions in /sup 27/Al, /sup 52/Cr, /sup 56/Fe, /sup 58,60/Ni, /sup 90,91,94/Zr, /sup 115/In, /sup 181/Ta, and /sup 197/Au have been measured for a proton energy 22.2 +- 0.2 MeV at angles 30, 60, 90, 120, and 150/sup 0/. The measurements were made in a time-of-flight neutron spectrometer at the 150-cm cyclotron at our institute. Analysis of the data shows that the nonequilibrium parts of the spectra are practically completely due to direct processes, which are responsible for the asymmetry in the neutron angular distribution.
