S007100100011 SAMPLE The tritium-charged Pd/Ti/Al samples were prepared by S007100100012 a conventional hydrogenation method, but using an S007100100013 apparatus which enables tritium gas to be handled. S007100100014 For Ta/TiHEx/Al samples, a new preparation method S007100100015 called the magnetron sputtering, and a uniform and S007100100016 surprisingly high concentration (1.87E17 atoms/cm2 S007100100017 He atoms in 5.3E17 atoms/cm2 Ti film) S007100100018 helium-titanium target was achieved. S007100100019 DETECTOR (SIBAR) The Au/Si surface barrier detector was placed S007100100020 at the appropriate laboratory backscattering angle S007100100021 and it subtended a solid angle of 1.12E-3 str by a S007100100022 defining slit of 3x4 mm. The angular and energy S007100100023 resolution of this detector system is about 1 S007100100024 degree and about 12 keV, respectively. S007100100025 MONITOR (46-PD-0(P,EL)46-PD-0,,DA,,RTH) The elastic scattering S007100100026 cross sections can obtained from the calculated proton S007100100027 Rutherford scattering cross section and the formula is S007100100028 showed as equation (1) in J,NIM/B,268,3373,201008. S007100100029 ERR-ANALYS (ERR-T,,7.3) total error associated with the cross S007100100030 sections is no larger than 7.3%. S007100100031 (ERR-S,2.,3.) The errors of AT and A(pd) result from S007100100032 statistical errors and background subtraction S007100100033 uncertainties in the T and Pd peak areas S007100100034 determination, and they are typically 2-3% in all S007100100035 cases less than 4%. S007100100036 (ERR-2,,1.) The error in Rutherford scattering cross S007100100037 section of Pd is less 1%. S007100100038 (ERR-3) The relative uncertainty of angle (1%) S007100100039 (ERR-4,,5.)
