STOPPING POWER FOR LOW-VELOCITY HEAVY-IONS - (0.01-0.9) MEV/NUCLEON SI IONS IN 18 (Z=13-79) METALS

The stopping power for Si-29 ions in Al, Ti, V, Fe, Co, Ni, Cu, Zn, Zr, Nh, Mo, Ag, Hf, Ta, W, Re, Pt and Au has been studied in the energy region (0.01-0.9) MeV/nucleon by application of a technique of nuclear physics, the inverted analysis of Doppler-shift attenuation data. Generally, the measured values are considerably higher at low energies (less than 0.4 MeV/nucleon) and show different energy dependence than the predictions of the commonly used empirical electronic stopping powers by Ziegler, Biersack and Littmark [1] [The Stopping and Ranges of Ions in Matter (Pergamon, New York, 1985) Vol. 1]. The uncertainty of the electronic stopping powers determined is typically +/-6%.
