Asymmetry of n- alpha scattering through an angle theta /sub n/ = 123 plus or minus 5 deg is measured for neutrons from the reaction up 3/ for E/sub d/ between 12 and 20 Mev. The analyzer employed was a gas helium chamber-- scintillator in coincidence with two neutron counters. In order to exclude geometric asymmetry effects the neutron spin was rotated over 90 deg in a magnetic field. In the T(p,n)He/sup 3/ reaction an asymmetry of 20% was observed at an angle of approximately 45 deg for all energies investigated. In the D(d,n)He/sup 3/ reaction the asymmetry at 30 deg reached (32.5 plus or minus 6.0)% at E/sub d/ = 14 Mev and with further increase of energy it slowly decreased. The directions of neutron polarization in both reactions were opposite. (auth)
