A150700100010 DETECTOR (MAGSP,PS) The cross sections were measured by using A150700100011 a magnetic spectrometer and 5x50 mm positive-sensitive A150700100012 detector with depletion depth of 120 micr. A150700100013 (NAICR) NaI(Tl) crystal was mounted outside the A150700100014 scattering chamber to serve as a monitor of the A150700100015 target condition. A150700100016 MONITOR (3-LI-7(P,A)2-HE-4,,DA) A150700100017 A lithium fluoride target was used to measure the A150700100018 absolute cross section of the Li7(p,alpha)He4 reaction A150700100019 at 0.880 MeV. A150700100020 The thickness of a LiF target was determined by A150700100021 measuring the width of the gamma-ray yield curve at A150700100022 the 0.872-MeV F-19(p,alpha+gamma)0-16 resonance. A150700100023 METHOD The absolute cross section at 880 keV calculated A150700100024 using knowledge of the stopping cross section A150700100025 of LiF for 88O-keV protons A150700100026 REL-REF (M,,M.Bader+,J,PR,103,32,1956) - the stopping cross A150700100027 section of LiF up to a proton energy of 600 keY A150700100028 (M,,C.Williamson+,R,CEA-2189,1962) Tables of A150700100029 calculated stopping cross sections A150700100030 ERR-ANALYS (MONIT-ERR) Uncertainty in cross section of monitor A150700100031 reaction. The largest uncertainty in the determination A150700100032 of the absolute cross section comes from a lack of A150700100033 knowledge of the stopping cross section of LiF for A150700100034 880-keV protons A150700100035 HISTORY (19800813C) Compilation produced by RFNC-VNIIEF Sarov A150700100036 (19990323U)CNPD: corrected 4-dig. year and lower cases.A150700100037 (20180128A) SD: Small correction in author's list.
