Electronic stopping powers for 80-350 keV F-19 ions in KTiOAsO4 (KTA) were obtained by range measurement. Depth profiles of F-19 in KTA were measured by using the F-19(p, alphagamma)O-16 resonant nuclear reaction at E-R = 872.1 keV, with width Gamma = 4.2 keV. A proper convolution calculation method was used to extract the true distributions of fluorine from the experimental excitation yield curves. The electronic stopping powers were derived through fitting the projected range distributions, simulated by using the TRIM/XLL code, to the experimentally measured range distributions. The electronic stopping cross sections were compared with those obtained from Monte Carlo simulation codes. (C) 2003 Elsevier B.V. All rights reserved.
