THE RANGE OF Cs137 IONS OF KEV ENERGIES IN GERMANIUM

Abstract
The range of Cs137 ions in germanium has been measured at 4-, 20-, and 40-kev bombardment energy. Two independent methods of determining the depth of penetration were used. The results are in reasonable agreement with our previous range measurements in aluminum, and with the recently published theoretical treatment of Lindhard and Scharff. A possible explanation has been found for the abnormally large value reported by Bredov for the penetration depth of 4-kev Cs134 ions in germanium.
