O055500100011 SAMPLE A gas target is a cylindrical box of approx. 10 liters O055500100012 volume. For tritium, a special box was built. O055500100013 All details see in original paper. O055500100014 DETECTOR (TELES,SOLST,SOLST) Delta E-E telescope. O055500100015 The recoil detector was a telescope made with two O055500100016 semiconductor detector, the first measured the energy O055500100017 loss and the other the remaining kinetic energy E. O055500100018 (SIBAR) Surface barrier detectors with thicknesses O055500100019 randing from 10 mum to 2 mm with an effective circular O055500100020 area of 1 cm**2. O055500100021 For the detection of He-3 above 60 MeV, added aluminum O055500100022 absorbers with thicknesses varying from 1 to 4 mm. For O055500100023 tritium, the range in silicon was equal to 2 mm for an O055500100024 energy of 28 MeV, at higher energies, germanium O055500100025 detector (1*1*2 cm**3,nip) which has a higher stopping O055500100026 power. O055500100027 FACILITY (SYNCY,2ZZZCER) CERN synchrocyclotron. O055500100028 METHOD (SITA) O055500100029 (EXTB) O055500100030 ADD-RES Invariant cross sections are given too in data table. O055500100031 MONITOR ((MONIT)13-AL-27(P,X)11-NA-24,CUM,SIG,,,EVAL) O055500100032 Cross section of the reaction was taken from CERN O055500100033 yellow report 60-3. O055500100034 ERR-ANALYS (EN-ERR).The uncertainty is reported by authors withoutO055500100035 any explanation. O055500100036 (ERR-T). Adding quadratically all the various O055500100037 independent uncertainties leads to a total systematic O055500100038 uncertainty about 10% in the elastic cross section. In O055500100039 addition, it should be noted that above 30-MeV for O055500100040 tritium, an additional error must be included as the O055500100041 germanium detector efficiency can only be determined O055500100042 with respect to the silicon detector efficiency, givingO055500100043 a total systematic uncertainty above 15%. O055500100044 (MONIT-ERR) From report for monitor cross section O055500100045 (ERR-1) The uncertainty of the absolute number of O055500100046 effective protons. The error includes the uncertainty O055500100047 in the activity measurements and the geometry of the O055500100048 beam monitor. The geometrical uncertainties in the O055500100049 recoil spectrometer are of the order of 4%. O055500100050 CORRECTION Multiple coulomb-scattering subtracts from the O055500100051 detection channel a part of the number of elastic O055500100052 events. This effect is negligible for 3-He and 4-He, O055500100053 but for tritium a correction has to be made up to 40 O055500100054 MeV mainly because of the window.
