F000300100009 FACILITY (CCW,1USALAS) 250 keV Cockcroft Walton accelerator F000300100010 METHOD The beam current was monitored by a microammeter. F000300100011 (PHD) F000300100012 DETECTOR (NAICR) To detect gamma-rays a large NaI phosphor F000300100013 photomultiplier detector (3.inch diam., 3.inch long) F000300100014 was placed outside the vacuum, at 90.degr. with respectF000300100015 to the incident beam, 5/8 inch from the target. F000300100016 (PROPC) Reaction charged particles which came off at F000300100017 90. degr were collimated and counted by a proportional F000300100018 gas counter. To make the assignment of possible F000300100019 reactions with particular groups of pulse heights, thisF000300100020 proportional counter could be replaced by a NaI crystalF000300100021 and photomultiplier.
