M063600100003 AUTHOR (G.J.O'Keefe,M.N.Thompson,Y.I.Assafiri,R.E.Pywell, M063600100004 K.Shoda) M063600100005 INSTITUTE (3AULAML,2JPNTOH) M063600100006 REFERENCE (J,NP/A,469,239,1987) M063600100007 INC-SOURCE Electron beam. M063600100008 FACILITY (LINAC,2JPNTOH) M063600100009 ANALYSIS The measured electrodisintegration reaction cross M063600100010 sections were related to the photoproton reaction M063600100011 cross sections by virtual photon theory. M063600100012 REL-REF (M,,I.C.Nascimento+,J,NP/A,246,210,1975) M063600100013 Virtual photon formalism. M063600100014 ERR-ANALYS (DATA-ERR) Mean-root-squared uncertainties are given. M063600100015 COMMENT The sum of the photoneutron and photoproton cross M063600100016 sections of 48Ca (48Ca(g,n) + 48Ca(g,p)) has been M063600100017 deduced from an activation yield curve measurements M063600100018 using bremsstrahlung. In a separate experiment the M063600100019 48Ca(g,p) and partial photoproton cross sections to M063600100020 the ground and first excited states of 47K have been M063600100021 deduced from measured photoproton spectra recorded M063600100022 from the electrodisintegration of 48Ca. The M063600100023 48Ca(g,n) cross section is estimated from these M063600100024 data. A statistical decay model is used to estimate M063600100025 the 48Ca(g,2n) cross section. These reported cross M063600100026 sections are used to determine the relative M063600100027 strengths and energy distributions of the isospin M063600100028 components of the GDR states, and to compare these M063600100029 with theoretical predictions. M063600100030 CRITIQUE In all cases of using the 48Ca(g,n+p) reaction M063600100031 designation in the article the really this is the M063600100032 sum of reactions 48Ca(g,n)47Ca and 48Ca(g,p)47K.
