S020400100010 SAMPLE Ta/TiHx/Si is used, and the atomic ratio of H to Ti S020400100011 in sample is above 150%. The areal density of H S020400100012 relative to Ta was determined by their scattering S020400100013 with 12C assuming Rutherford scattering. S020400100014 DETECTOR (SIBAR) The RBS detector was fixed at the laboratory S020400100015 backscattering angle of 165degree and it subtended a S020400100016 solid angle of 1.83E-3 sr. The ERD detector was fixed S020400100017 at the laboratory recoil angle of 30 degree and it S020400100018 subtended a solid angle of 1.12E-3 sr. S020400100019 ERR-ANALYS (ERR-T,,5.2) Total uncertainty is less than 5.2%.
