M057200100004 AUTHOR (N.d'Hose,G.Audit,A.Bloch,N.de Botton,L.Jammes, M057200100005 J.M.Laget,J.Martin,E.Mazzucato,A.Sasaki,C.Schuhl, M057200100006 G.Tamas,L.Ghedira,M.Rodgers,P.Stoler,P.Argan, M057200100007 P.Pedroni) M057200100008 REFERENCE (J,PRL,63,856,1989) M057200100009 INSTITUTE (2FR SAC,1USARPI,2ITYPAV) M057200100010 FACILITY (LINAC,2FR SAC) The Saclay linac. M057200100011 INC-SOURCE (QMPH,ARAD) M057200100012 METHOD (MAGFR) "700" Magnetic spectrometer. M057200100013 DETECTOR (SCIN) M057200100014 ANALYSIS The cross section were obtained by comparing the M057200100015 simulated using Monte Carlo simulation photoproton M057200100016 energy distributions with the experimental spectra. M057200100017 ERR-ANALYS (DATA-ERR) No information about sources of M057200100018 uncertainties. M057200100019 COMMENT Cross sections were determined in the delta (1232) M057200100020 excitation region for the reactions 3He(gamma,p)pn andM057200100021 2H(gamma,p)n at several photon energies and proton M057200100022 emission angles. Inclusive proton spectra were M057200100023 measured with a magnetic spectrometer, using a M057200100024 quasimonochromatic e+ - annihilation photons. The M057200100025 3He data can Be mainly accounted for by predictions M057200100026 assuming photon absorption by a pair of nucleons, M057200100027 except in the high-momentum parts of the proton M057200100028 spectra. They clearly indicate the need for M057200100029 additional contributions, such as three-body M057200100030 absorption mechanism.
