A086100100016 SAMPLE Silicon plates of natural isotopic composition, A086100100017 0.5-to 3 mug/cm**2 in thickness were used as targets.A086100100018 ADD-RES (COMP).The collective-excitation mechanism and the A086100100019 coupled-channel method. A086100100020 DETECTOR (SIBAR) The angular dependences of the differential A086100100021 cross sections were measured in an individual A086100100022 experiment by a semiconductor surface-barrier detector A086100100023 arranged beyond the scattering chamber. In that case, A086100100024 scattered alpha particles escaped from the scattering A086100100025 chamber through a horizontal slit covered with a thin A086100100026 20 mum Mylar window. In measuring double-differential A086100100027 cross sections, four silicon semiconductor surface- A086100100028 barrier detectors (SBD) with a sensitive area up to A086100100029 400 mum in thickness were used. The detectors were A086100100030 arranged with in the scattering chamber 230 mm in A086100100031 diameter on a table whose angle of inclination with A086100100032 respect to a horizontal plane could be changed. A086100100033 (NAICR). Gamma rays were detected by four scintillationA086100100034 detectors BDEG-23 based on NaI(Tl) crystals 63 mm in A086100100035 height and diameter A086100100036 PART-DET (A,G) A086100100037 METHOD (BCINT) A086100100038 ERR-ANALYS The error in the absolute values of the differential A086100100039 cross section was on average about 20% and was A086100100040 determined primarily by the uncertainties in measuring A086100100041 the target thickness and in calibrating the current A086100100042 integrator.
