O164600100027 The separation of the secondary beams was made by meansO164600100028 of the doubly achromatic spectrometer LISE. O164600100029 DETECTOR (TELES,SI,SILI) A 300 mum Si-detector, mounted in frontO164600100030 of the secondary reaction target. After the reaction O164600100031 target, a delta-E-E telescope, composed of a 300 mum O164600100032 Si and a 5000 mum Si(Li) detector, was installed for O164600100033 particle identification. O164600100034 (SCIN) A total of 23 liquid-scintillation neutron O164600100035 detectors were placed 3 m down-stream from the target.
