M0691 1 18 METHOD (EXTB,SITA) Experimental reaction yield measurement M0691 1 19 from 8 to 29 MeV with bin 0.1 MeV. M0691 1 20 ANALYSIS (PLA) The effective cross section was obtained M0691 1 21 with an analysis bin 1 MeV. Up to 25 MeV cross M0691 1 22 section was calculated from the yield curve on M0691 1 23 which the data point were spaced 200 keV apart and M0691 1 24 above 25 MeV - 500 keV. M0691 1 25 ERR-ANALYS (DATA-ERR) The mean-root-square errors. M0691 1 26 STATUS (APRVD) By V.V.Varlamov. M0691 1 27 COMMENT Using bremsstrahlung from the 35 MeV betatron the M0691 1 28 26Mg(g,xp) reaction cross section has been obtained M0691 1 29 in the excitation energy region up to 29 MeV. The M0691 1 30 data were used for discussion of the role of isospin M0691 1 31 splitting in the formation of 26Mg giant dipole M0691 1 32 resonance.
