Fast neutron capture cross sections were measured in the energy interval from 0.02 to 0.7 MeV using white source neutron time-of-flight techniques and from 0.3 to 3.0 MeV using monoenergetic neutrons. Target materials were Co, Ni, Zn, Cu, Nb, Ho, Ta, Au and /sup 238/U. A 1300 1 liquid scintillator was used as a capture ..gamma..-ray detector. Flat efficiency neutron detectors and/or the standard capture cross section of Au were used for the neutron flux determination. Fast neutron capture and activation cross sections were calculated in terms of the statistical model. The Hauser-Feshbach formalism and a gamma cascade model previously described were used. 5 figures (auth)
