“…A comparison of elastic recoil detection (ERD) using 12 MeV F 4+ ions, nuclear reaction analysis (NRA) based on the 11 B(p, a) 8 Be* reaction and SIMS for samples implanted with 0.3-10 keV 11 B + at a fluence of 10 13 -10 16 ions cm À2 showed that the accuracy of SIMS data strongly depended on the conditions used. 172 Specifically, 500 eV O 2 + oxygen sputtering at an incidence of 601 in the absence of oxygen flooding yielded accurate results within a few %, but 0.7 or 1 keV projectiles at an incidence angle of 451 or 601, respectively, with oxygen flooding gave deviations of up to 20%.…”
