C087800100010 INC-SPECT Energy resolution represents net effects of target C087800100011 thickness, straggling, detector resolution, and C087800100012 position resolution. C087800100013 SAMPLE Natural lithium targets deposited on formvar backings, C087800100014 300 to 400 keV thick to incident beam. C087800100015 METHOD (EDE) C087800100016 DETECTOR (TELES,SOLST) Two counter telescopes consisting of C087800100017 silicon detectors set at 18.5 degrees. C087800100018 MONITOR Detectors calibated using alphas from 228Th radioactiveC087800100019 source at low energies, and 12C(12C,alpha) reaction C087800100020 at beam energies of 25 and 45 MeV. C087800100021 CORRECTION Data corrected for background and detector efficiency. C087800100022 ERR-ANALYS (DATA-ERR) Uncertainties given arise from combining: C087800100023 . statistical uncertainties in the number of counts in C087800100024 each angular bin above background and from the C087800100025 background itself; C087800100026 . uncertainty in detector efficiency correction.
