C098700100009 INC-SPECT Energy calculated assuming energy loss for deuterons C098700100010 in 3He was the same as that in 4He. C098700100011 SAMPLE 3He contained in flat cylinder. Gas pressure about 85 C098700100012 mm Hg at deuteron energies of 0.978-3.56 MeV and 25 C098700100013 mm at deuteron energies of 0.240-0.978 MeV. C098700100014 PART-DET (P) C098700100015 DETECTOR (NAICR) C098700100016 METHOD (BCINT) Four runs taken at each energy and angle. C098700100017 Since only a few standard cm3 of He3 were available C098700100018 for this experiment, it was necessary to concentrate C098700100019 as much as possible of the He3 reaction volume. This C098700100020 was accomplished by collimating the deuteron beam, C098700100021 and detecting protons formed in the reaction, outside C098700100022 the region containing the He3. The NaI crystal was C098700100023 1/8 in. thick, which was sufficient to stop the C098700100024 protons and at the same time thin enough that the C098700100025 background from neutrons and gamma-rays was negligible.C098700100026 Light pulses from the sodium iodine crystal were C098700100027 detected in a type 5819 photomultiplier tube and the C098700100028 resulting electrical pulses were amplified and C098700100029 recorded on a 10-channel pulse-height analyzer. C098700100030 CORRECTION Below 1.51 MeV, corrected for effects of multiple C098700100031 scattering of deuteron beam in entrance window.
