A059900100004 AUTHOR (J.Raisanen, E.Rauhala) A059900100005 REFERENCE (J,NIM/B,73,439,1993) A059900100006 INSTITUTE (2SF HLS) Accelerator Laboratory. A059900100007 SAMPLE The aluminum, silicon and titanium samples were A059900100008 prepared by vacuum evaporation of thin layers of A059900100009 natural Al (thickness = 100 nm), Si (100 nm) and Ti (75A059900100010 nm) on carbon substrates and further thin layers of A059900100011 gold (25 nm) were evaporated on these films. The gold A059900100012 film was to serve as an internal ion dose reference. A059900100013 To enable the subtraction of the background yields A059900100014 generated by the carbon substrates, also a pure carbon A059900100015 target was used. A059900100016 MONITOR (79-AU-197(3-LI-7,EL)79-AU-197,,DA) A059900100017 PART-DET (3-LI-7) A059900100018 DETECTOR (SIBAR) A silicon surface barrier detector positioned A059900100019 at a scattering angle of 170 degree. The solid angle A059900100020 suspended by the collimated detector was 2.76 msr. TheA059900100021 energy resolution of the detection system was 28 KeV atA059900100022 E(Li) = 3.0 Mev. A059900100023 FACILITY (VDGT,2SF HLS) Tandem accelerator EGP-10-II A059900100024 METHOD (SITA) A059900100025 (EXTB) The 7-Li beam charge states of + 1 were used A059900100026 below 7 MeV and + 2 for the higher energies. A059900100027 HISTORY (20040130C) A059900100028 (20040202U) Last checking has been done. A059900100029 COMMENT - By authors. The cross section measurements were A059900100030 repeated at regular intervals at low reference energiesA059900100031 to check for possible changes in the target A059900100032 compositions. No changes, however, were observed. A059900100033 ERR-ANALYS (ERR-T) The uncertainties given in data sections are A059900100034 due to the statistical error in the peak areas and the A059900100035 possible error in the background subtraction. The A059900100036 reaction yield background from the carbon substrate A059900100037 increases with ion energy, rendering the high energy A059900100038 background subtraction less accurate.
