A805,528,2008 - vol. not published D604900100016 FACILITY (VDG,3INDNSD)15UD Pelletron at the IUAC,New Delhi. D604900100017 SAMPLE Enriched, isotopic W-184 target of thickness 210 D604900100018 microgm/cm2 on a 110 microgm/cm2 carbon backing was D604900100019 used. As the residues were of low energy (5.5 to 8 D604900100020 MeV),the carbon foil was made to face the beam to D604900100021 avoid energy loss of residues in carbon foil. D604900100022 DETECTOR (BGO) 14 BGO detectors were used with seven detectors D604900100023 at the top and the remaining seven at the bottom. D604900100024 (SIBAR) Elastically scattered oxygen ions were D604900100025 registered in two Si surface barrier detectors placed D604900100026 at 25 degree with respect to the beam direction. D604900100027 (HPGE) A high resolution HPGe detector of 23% D604900100028 relative efficiency was mounted at the target D604900100029 chamber. Gamma rays were recorded by the HPGe detector D604900100030 in singles and in coincidence with ERs. D604900100031 METHOD (TOF,GSPEC)A pulsed beam, with a pulse separation of D604900100032 4 microsec was used to record the time of flight D604900100033 (TOF) of slowly moving residues. The start signal for D604900100034 TOF was taken from focal plane Si detector and the D604900100035 stop signal was the RF used for pulsing, with 4 D604900100036 microsec pulse separation. The (TOF) setup gave a D604900100037 clean separation of ERs from the beam like particles. D604900100038 The transmission efficiency of HIRA was determined by D604900100039 the gamma ray method at 100 MeV beam energy.
