Stopping cross-section measurements of 4He in TiN1.1O0.27
Abstract The stopping cross-section for 4He projectiles in TiNx compounds has been measured using the backscattering method. A multi-compound marker layer deposited between the test film and the substrate was used to obtain the stopping cross-section at several energies with one energy of the incident beam. Two RBS spectra at definite tilt angles of the sample are taken for each beam energy. The assistance of computer codes to synthesize RBS spectra is very useful to obtain the pertinent information from the displacements of the peaks of the marker layers. Stopping cross-section values are obtained with an estimated uncertainty of about 6%.
Stopping power measurement of 48Ca in a broad energy range in solid absorbers
Abstract Stopping power of 48 Ca ions in C, Ni and Au was measured using TOF-E method. The results cover energy range from 0.1 to 5.3 MeV/u (5–250 MeV). The reliability of our experimental method was verified and confirmed by TOF–TOF measurements. The results are compared with theoretical (PASS) and semi empirical (SRIM2003) predictions.
