O227200100023 SAMPLE H(2) target of about 10E+13 particles/cm**2, O227200100024 a luminosity of about 2*1025/cm**2/s has been O227200100025 achieved. O227200100026 ANALYSIS The (p,g) cross section can be normalized O227200100027 by two methods using the theoretical single EC cross O227200100028 section and the calculated K-REC cross section at 90 O227200100029 degree. The single EC cross section and the K-REC crossO227200100030 section can be predicted very well by different O227200100031 theoretical models.There are large uncertainties, aboutO227200100032 30%, in accurately determining the absolute beam O227200100033 intensities, target densities, and beam-target overlap O227200100034 at the ESR. To remove these large uncertainties, both O227200100035 the K-shell REC(radiative electron capture,accompanied O227200100036 by the emission of a photon) products (photons) and theO227200100037 EC products were registered by our detectors, which O227200100038 allowed to absolutely determine the (p,g) cross sectionO227200100039 using two normalization methods.

O227200100050 The uncertainty of the (p,g) cross section is dominatedO227200100051 by the uncertainty of the calculated K-REC or EC cross O227200100052 section-20% and the uncertainty of N(pg) approx.20%, O227200100053 while the uncertainty of other factors is always less O227200100054 than 10%.
