Prompt gamma-ray and x-ray spectroscopy techniques are being employed to study fission induced on {sup 238}U targets by neutrons of energy from 1 MeV to 150 MeV. Data are acquired using the GEANIE high resolution gamma-ray spectrometer at the LANSCE/WNR unmoderated spallation neutron source. Information on the pre-decay yields (excitation functions and isotopic distributions) were extracted from gamma and gamma-gamma coincidence data for a wide range of nucleides. Charge yields were extracted by measuring prompt x-rays from a thin, fission-sensitive target using photovoltaic cells specially designed. The experimental results are presented and compared to model calculations.
