Stopping force of Ti for 6 ⩽ Z ⩽ 29 ions measured by time of flight spectrometry

Accurate stopping force data is of vital importance in ion beam materials analysis using heavy ion beams. The predictive accuracy of theoretical and semi-empirical formulations can only be improved through continual validation of these codes by making available experimental data from a wide range of projectile-target combinations. In this work stopping force measurements of Ti for 12C, 16O, 24Mg, 27Al and 63Cu ions were carried out by heavy ion Time-of-Flight Elastic Recoil Detection (ToF-ERD) spectrometry and the results are compared with semi-empirical calculations by Ziegler's Stopping and Range of Ions in Matter (SRIM-2010) code, and ab initio calculations by Grande and Schiewietz's Convolution approximation for swift Particles (CasP 5.2) code. Both SRIM and CasP underestimate stopping in the energy range studied. SRIM predictions average within 10% of data and CasP calculations range within 5-25% of data.
