M061000100004 AUTHOR (H.Tsubota,S.Oikawa,J.Uegaki,T.Tamae) M061000100005 REFERENCE (J,NP/A,303,333,1978) M061000100006 #doi:10.1016/0375-9474(78)90362-7 M061000100007 INSTITUTE (2JPNTOH) M061000100008 FACILITY (LINAC,2JPNTOH) M061000100009 INC-SOURCE (VPH) M061000100010 DETECTOR (MAGSP,SILI) Browne-Buchner type broad-range magnetic M061000100011 spectrometer with 100 Si(Li) solid-state detectors M061000100012 in the focal plane. M061000100013 ANALYSIS (LEAST,INTAD) The Cook least-square method for (g,p) M061000100014 reaction differential cross section obtaining from M061000100015 (e,e'p) reaction cross sections measured using the M061000100016 direct proton detection with the following M061000100017 integration over angles. M061000100018 ERR-ANALYS (DATA-ERR) Root-mean-squared errors. M061000100019 COMMENT The differential cross sections of the (e,e'p) M061000100020 reactions for 51V and 59Co have been measured at M061000100021 90-deg over the region of excitation corresponding M061000100022 to the electric giant dipole resonance. The (g,p) M061000100023 cross sections of these nuclei were deduced from M061000100024 differential cross sections assumed isotopic angular M061000100025 distributions of protons. The results are compared M061000100026 with the (g,n) cross sections, and are used to M061000100027 obtain strengths of the T< and T> giant dipole M061000100028 states separately by using the statistical theory. M061000100029 For each nucleus the ratio of the separated M061000100030 strengths and the splitting energy are consistent M061000100031 with those expected by isospin formalism.
