Abstract : The objectives of this contract were to carry out basic research in the areas of neutron spectroscopy and dosimetry, gamma-ray spectroscopy and dosimetry, and activation analysis techniques. Early work in gamma-ray spectroscopy was done mostly with the bent crystal spectrometers and the triple coincidence scintillation spectrometer which were used in capture gamma-ray studies. Later, however, all the work in gamma-ray spectroscopy was in the development and application of lithium drifted Ge(Li) solid state detectors. A description is included of the fabrication techniques used and the application of these detectors to the study of capture gamma-rays and spent reactor fuel. Work on problems of neutron spectroscopy and dosimetry are described. This work resulted in an improved method for measuring fast neutron spectra through the use of foils. The work done in activation analysis is summarized.
