O108100100014 ADD-RES (COMP) O108100100015 The distorted wave Born approximation calculations. O108100100016 He-3 energy spectra were analyzed. O108100100017 SAMPLE A 100-mm diameter gas cell, filled with helium, more O108100100018 99.995% purity, to a nominal absolute pressure of 1.5 O108100100019 bar at room temperature, was bombarded with alpha- O108100100020 particles. O108100100021 The effective target length and solid angle were O108100100022 defined by means of a double-aperture collimator systemO108100100023 with 3-mm thick tantalum front and rear slits. The O108100100024 slits were placed 186 and 526-mm, respectively, from O108100100025 the center of the target. The rather large distance O108100100026 from the gas cell and large separation between slits O108100100027 ensured that measurements could be performed down to O108100100028 very forward angles with small effective target and O108100100029 good angular resolution. At forward angles smaller thanO108100100030 26-degree, 2.8 mm wide slits were used, while 4.5-mm O108100100031 wide slits were employed at larger angles in order to O108100100032 increase the count rate. The effective target length O108100100033 varied between 8 and 28-mm, i.e., Weel distant from theO108100100034 6-mum thick HAVAR entrance and exit windows of the gasO108100100035 cell. O108100100036 DETECTOR (TELES) Different detector telescopes were used in the O108100100037 158- and 200-MeV measurements. For the 158-MeV runs O108100100038 the telescope consisted of a 150-mum thick Si surface O108100100039 barrier delta-E detector, followed by two Si-Li O108100100040 detectors of 5-mm nominal thickness each, followed by aO108100100041 1-mm thick Si surface-barrier veto detector. O108100100042 For the 200-MeV runs the front delta-E element was O108100100043 replaced with a 2-mm thick Si surface-barrier detector.O108100100044 The standard delta-E-E technique was used for particle O108100100045 identification.
