A millimicrosecond time-of-flight technique was applied io a study of the scattering of 2.2-Mev neutrons from targets of Fe, Pb/sup 206/,. and Y. The 3- Mev phasefocused proton beam from the BNL 18-inch cyclotron was used to produce high-intensity neutron pulses in ihe T(p,n)He/sup 3/ reaction. The angular distributions of the elastically scattered neuirons have been meas:ired for the above targets. The angular distributions of the inelastically scattered neutrons from the 0.845-Mev level in Fe/sup 56/ and from the 0.803-Mev level in Pb were carefully studied and found to be symmetric about theta /sub c.m. = 90 deg . The angular distributions of the inelastically scattered neutrons from levels at 1.34 and 1.43 Mev in Pb/sup 206/ and from levels at 0.913 and 1.53 Mev in Y were measured and also appear to be symmetric about theta /sup c.m./ = 90 deg The inelastic scattering from Pb/sup 206/ shows evidence for a new level at 1.15 Mev.
