Both gold-silicon surface barriers and silicon p-n junctions operated satisfactorily as particle spectrometers. The use of high-resistivity material gave a depletion region wide enough to stop high-energy protons, alpha particles, and heavier ions. A resolution of 16 kev (width at halfmaximum) for 6.04 Mev a particles was obtained with a junction depletion layer sufficient to stop 10 Mev alpha particles. With the depletion region very close to the surface, beta particles in the range from 10 to several hundred kev were detectable. The pulse amplitude distribution from Co/sup 57/ indicated the presence of the two well-known lines at 115 and 129 kev. An attempt was made to correlate the observed performance with the semiconductor parameters and the diode static characteristics. (auth)
