Abstract

An experiment employing a new method of measuring stopping power at low energies is described, and results are given for protons on gold. Values of $\frac{dE}{dx}$ for protons on gold have been obtained from measurements of the reponse of a silicon surface-barrier detector, covered with a surface layer of gold, to protons of energy below 50 keV. The response of the detector to $H_{2}^{+}$ and $H_{3}^{+}$ ions in the same energy range has been used to determine backscattering cross sections for protons on gold.
