Abstract : A relatively inexpensive cryostat was constructed for operation of lithium drifted germanium gamma ray detectors at pressures below 0.0000001 mm of Hg and at 77K. Fundamental data was obtained on a Li drifted Ge detector, including relative counting efficiency, resolution and peak to total ratio. The spectra of Ir192 and Ag105 were investigated using the solid state detector. A technique of segmentation and expansion of energy subgroups with a multichannel analyzer is offered as a means to provide more points in a given peak of a spectrum taken on the detector.
