A large number of partial {gamma}-ray cross sections produced in neutron-induced reactions with neutrons in the energy range 1 < En (MeV) < 200 have been measured over the past eight years. Partial {gamma}-ray cross sections are measured as a function of incident neutron energy using the time-of-flight technique. Reaction channel cross sections were deduced from these measurements with the aid of nuclear modeling. Enabling facilities are the intense 'white' source of neutrons at the LANSCE/WNR 60R 20-meter flight path, and the precision {gamma}-ray spectrometry of the Compton-suppressed Ge detector array GEANIE. The first focus of the measurements was on the 239Pu(n,2n) cross section, followed by a series of other experiments on nuclei throughout the periodic table, with an emphasis on neutron-fluence activation detectors (or 'RadChem detectors'). Representative measurements will be presented, along with the techniques. Experiments in progress and future plans are mentioned.
