Resolution Limitation of Solid State Radiation Detectors for Heavy Particles

Abstract

The resolutions of semiconductor detectors were measured for protons, deuterons, ¿ particles and 4He+ ions at different energies between 20 keV and 5.5 MeV. We obtained limits of the Fano factor and evaluated the contribution of nuclear collisions to the half-maximum width of the ¿ particle peaks. The latter result is compared with LINDHARD and NIELSEN's calculations. Moreover we measured differences between electron-hole pair creation energies for the different particles.
