C175500100012 SAMPLE Self-supporting Si target with thickness of C175500100013 311 mu-g/cm2 C175500100014 DETECTOR (MAGSP)The reaction products were momentum analyzed C175500100015 using an Enge split-pole spectrograph. C175500100016 (TELES,DRFTC,SCIN)Reaction products were detected at C175500100017 the focal plane of the magnetic spectrograph by a C175500100018 position-sensitive ionization drift chamber (PIDC) C175500100019 filled with 150 torr of isobutane gas, backed by a C175500100020 plastic scintillator.The PIDC was used to measure C175500100021 position along the focal plane via front and rear C175500100022 wires with delay chip readouts, and energy loss in C175500100023 the drift region dE, via a cathode. Scintillator was C175500100024 used to determine the residual energy of the particles.C175500100025 (MAGSP)The reaction products were momentum analyzed C175500100026 using an Enge split-pole spectrograph. C175500100027 (SISD)Protons emitted from excited states in 27Si C175500100028 were detected by the Yale lamp-shade array, an array C175500100029 of five 16-strip silicon detectors arranged in a C175500100030 lamp-shade configuration. C175500100031 Definition of angles C175500100032 ANG1 - Laboratory angle of split pole Enge C175500100033 spectrograph, used to detect alpha particles. C175500100034 The spectrograph was placed at a 3deg angle with C175500100035 respect to the beam axis to avoid prohibitively large C175500100036 event rates due to the forward scattered beam at C175500100037 0 deg to 2 deg. C175500100038 ANG2-CM - CM angle of proton, detected in Yale C175500100039 lamp-shade array C175500100040 METHOD (EDE,COINC) C175500100041 ERR-ANALYS (DATA-ERR) Total uncertainty. Main source of C175500100042 uncertainty was background determination in the total C175500100043 focal-plane spectrum, which was much larger than any C175500100044 systematic or statistical errors in the measurement.
