Heavy ions, accelerated at energies below 250 keV are used to study the stopping powers (dE/dx) of thin carbon foils and their angular behavior. Energy losses are measured with a high-resolution magnetic spectrometer. Our results are compared with other experiments and with the Lindhard--Scharff--Schiott (LSS) theory. Discrepancies with the LSS theory increase at low energies for a given ion, and with increasing Z$sub 1$ at a given energy. For angular studies of the stopping power we obtain a characteristic curve dE/dx(theta), and find that its behavior can be related to the thickness of the foil (4 to 14 $mu$g/cm$sup 2$) and to the incident energy (40 to 240 keV) for Ar ions.
