O138100100025 (R,O1171001,U.GREIFE+,J,ZP/A,351,107,1995) The data O138100100026 were used for normalization. O138100100027 HISTORY (20060412C) O138100100028 (20060420U) Last checking has been done. O138100100029 SAMPLE Each deuterated target was produced in the folowing O138100100030 way. A fresh materials with a purity of better than O138100100031 99% was bombarded with 10-KeV deuterons, whereby the O138100100032 proton yield of d(d,p)t was recorded as a function of O138100100033 implantation charge. The yield reached usually a O138100100034 saturation level after a charge of about 1 Coulomb. O138100100035 The procedure was repeated at Ed = 30-KeV. For most ofO138100100036 The materials the distribution was uniform within 10% O138100100037 from the surface down to depth consistent with the O138100100038 range of the implanted deuterons. O138100100039 ADD-RES Summary of screening potentials for 34 materials. O138100100040 DETECTOR (SIBAR) Four Si detectors, active area=600 mm**2, O138100100041 effective thickness=100-mum were used. O138100100042 FACILITY (VDGT,2GERBOC) The 100 kV accelerator. O138100100043 METHOD (BCINT,SITA) O138100100044 (EXTB) Used accelerator provided the deuteron beam, O138100100045 with 54 microampers on target. O138100100046 COMMENT -By author: O138100100047 1. The reaction yield of the infinitely thick target O138100100048 was obtained in several runs at E/d = 5 to 30 KeV with O138100100049 energy step at 0.5 KeV at E/d =5 to 10 KeV and 1.0 KeV O138100100050 at E/d = 10 to 30 KeV. The energy step correspond to O138100100051 about 50 and 100 atomic layers near the surface. O138100100052 2. The absolute scale was obtained by normalization to O138100100053 revious work (see REL-REF) at 30 KeV including the O138100100054 effects screening where applicable. The normalization O138100100055 led to a value for the stoichiometric ratio. O138100100056 3. The resulting cross section is the weighted average O138100100057 of several runs. O138100100058 ANALYSIS (UNFLD) In order to arrive at a thin target yield O138100100059 curve, the thick-target yield curve was differentiated.O138100100060 PART-DET (P) O138100100061 ERR-ANALYS (DATA-ERR) The error is shown by authors on figure.
