ENTRY C1992 20220805 C216C199200000001 SUBENT C1992001 20220805 C216C199200100001 BIB 10 35 C199200100002 TITLE Gamma Rays from the Proton Bombardment of N15 C199200100003 AUTHOR (S.Bashkin,R.R.Carlson) C199200100004 REFERENCE (J,PR,106,(2),261,1957) C199200100005 #doi:10.1103/PhysRev.106.261 C199200100006 INSTITUTE (1USAIOW) C199200100007 FACILITY (VDG,1USAIOW) C199200100008 PART-DET (P,G) C199200100009 DETECTOR (NAICR,BF3) Gamma rays were detected with a Harshaw, C199200100010 NaI(Tl) crystal, three inches in diameter and three C199200100011 inches long, optically coupled to a Dumont 6363 C199200100012 photomultiplier tube. C199200100013 SAMPLE (7-N-15,ENR=0.61) Nitrogen gas. C199200100014 METHOD (GSPEC) Protons were accelerated with a pressurized, C199200100015 electrostatic generator. A variable magnetic field C199200100016 deflected the beam 25 degrees through collimating C199200100017 apertures, the smallest of which was 0.080 inch x 080 C199200100018 inch in size, into the target chamber. The magnet C199200100019 current was calibrated against proton energy by C199200100020 measuring the current at which well-known resonances C199200100021 in the 19F(p,alpha gamma)150 reaction appeared when C199200100022 monatomic and diatomic hydrogen ions struck thin, C199200100023 fluorine targets. In addition, a BF3 counter was used C199200100024 to locate the known threshold for the 15N(p,n)150 C199200100025 reaction at 3776 kev. The proton energy was known C199200100026 absolutely to +- one percent over the range of this C199200100027 experiment. Data were taken with targets of nitrogen C199200100028 gas prepared from ammonium nitrate. The yield curve C199200100029 for reaction 15N(p,alpha gamma)12C was measured by C199200100030 detecting the 4.43-Mev gamma rays resulting from the C199200100031 fast de-excitation (half-life < 3x10-13 sec) of the C199200100032 12C nucleus. Since the gamma-ray energy was C199200100033 independent of the bombarding energy, the detection C199200100034 efficiency was constant for a given geometry.

C199200300006 to the previous absolute measurements. By using the C199200300007 one-level formula, the new resonances at 3000 keV, C199200300008 3300 keV, and 3520 keV were extrapolated far enough C199200300009 away from their resonance positions for their C199200300010 contributions to the yield to be negligible.
