It was O186700100025 isotopically pure to 99%. Its thickness was a O186700100026 compromise between count rate and energy resolution. O186700100027 It was optimized to 100 mum, which corresponds to an O186700100028 energy resolution of 1 MeV. O186700100029 COMMENT *By authors*.It was not possible to separate and to O186700100030 distinguish between the ground state and the first O186700100031 excited state of Be-7. O186700100032 The number of Be-7 nuclei is expected to be small so O186700100033 that particle identification is important to O186700100034 distinguish between frequent background and rare O186700100035 events. Therefore, particle identification was O186700100036 performed by redundant methods. O186700100037 DETECTOR (MAGSP) The recoiling Be-7 nuclei were detected with O186700100038 the magnetic spectrograph Big Karl (see Rel-Ref) O186700100039 (MWPC) Detectors used to measure the reaction-product O186700100040 position, and their emission direction was two O186700100041 multiwire avalanche chambers (MWACs), each of size O186700100042 70*8 cm**2. O186700100043 (SCIN) Two layers of plastic scintillators. The first O186700100044 one was a bar with dimensions 60*8 cm**2. It had a O186700100045 thickness of 0.5 mm and served as a delta-E detector asO186700100046 well as a start detector for a TOF measurement. O186700100047 The second layer was a stack of four scintillators O186700100048 of 70*2 cm**2, each 2-mm thick. It served as an O186700100049 E-detector as well as a stop detector for the TOF O186700100050 measurement.
