In this paper new experimental data are presented for the stopping power of Ti, V and Cr ions in Ge and Au, in the 150–500 keV/u energy range. The heavy ions at low energies are produced from the elastic scattering between particles of an energetic

The Saci-Perere γ ray spectrometer (located at the Pelletron AcceleratorLaboratory - IFUSP) was employed to implement the γ-particle coincidence technique for the study of nuclear reaction mechanisms. For this, the 18O+110Pd reaction has been studi

The stopping power of Au for Cu in the energy range 6 < E < 25 MeV was measured using a secondary beam of low velocity heavy ions produced by elastic scattering of an energetic primary beam (typically 28 Si or 16 O) on a natural Cu target. The result
