The normalization factors for two sets of global optical model parameters were compared in order to estimate the uncertainties involved in this method. Optical model parameter [F.D. Becchetti, Jr. and G.W. Greenlees, Phys. Rev. 182(1969)1190] were adopted. /; EMT=P; ENGY-EMT-CM=12.0MEV; /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; THTL DSIGMA/DOMEGA/DE DELTA-DSIGMA/DOMEGA/DE'401' (DEG) (MB/SR/MEV) (MB/SR/MEV) 30.0 1.824 +-0.091 40.0 1.606 +-0.024 50.0 1.339 +-0.018 60.0 1.118 +-0.017 70.0 0.925 +-0.015 80.0 0.825 +-0.014 90.0 0.721 +-0.010 100.0 0.597 +-0.009 110.0 0.507 +-0.009 120.0 0.461 +-0.008 130.0 0.419 +-0.008 140.0 0.371 +-0.007 150.0 0.367 +-0.007 160.0 0.338 +-0.007 \END; /*===================================================================*/ |
