M046300100004 AUTHOR (D.M.Skopik,Y.M.Shin,M.C.Phenneger,J.J.Murphy) M046300100005 REFERENCE (J,PR/C,9,531,1974) M046300100006 #doi:10.1103/PhysRevC.9.531 M046300100007 INSTITUTE (1CANSAS) M046300100008 FACILITY (LINAC,1CANSAS) M046300100009 INC-SOURCE (VPH) Virtual photons. M046300100010 METHOD (MAGFR) M046300100011 SAMPLE A deuterium gas was contained in a right circular M046300100012 cylinder of 2.54 cm radius and 3.5 cm height. The M046300100013 walls were 0.00064 cm havar foil. The target cell M046300100014 was designed to be filled to a pressure of 2.0 atm. M046300100015 PART-DET (P) M046300100016 DETECTOR (MAGSP,SOLST) Five surface-barrier silicon detectors M046300100017 mounted in the focal plane of 127-degrees M046300100018 doublefocusing magnet. M046300100019 ANALYSIS The proton angular distribution data were taken at 12 M046300100020 photon energies. In addition an angular distribution M046300100021 covering 19 angles was measured for Eg = 20.0 (0.25) M046300100022 MeV. The equivalent photon cross sections have been M046300100023 extracted from the electrodisintegration data using M046300100024 the virtual photon spectrum technique. M046300100025 COMMENT The equivalent photon cross sections were extracted M046300100026 from deuteron electrodisintegration measurements M046300100027 over an energy range of 17 to 28 MeV. Proton angular M046300100028 distributions were measured at 12 photon energies M046300100029 and the total cross section determined with an M046300100030 experimental uncertainty of approximately lower than M046300100031 6%. The differential cross section at angle-cm = 90 M046300100032 degrees was also measured.
