微分截面的反应已被测量与A2标记光子设施在美因茨的Microtron，MAMI C，直到质心的能量。新的结果，获得了一个很好的能量和角面元，增加了现有的数量的光生数据。由于前所未有的统计精度和全角度覆盖，结果对高分波振幅敏感。这是证明了由勒让德多项式的微分截面的分解和模型预测的进一步比较。本文提出了一种新的SAID分波分析方法。
Differential cross sections for thereaction have been measured with the A2 tagged-photon facilities at the Mainz Microtron, MAMI C, up to the center-of-mass energy. The new results, obtained with a fine energy and angular binning, increase the existing quantity ofphotoproduction data by. Owing to the unprecedented statistical accuracy and the full angular coverage, the results are sensitive to high partial-wave amplitudes. This is demonstrated by the decomposition of the differential cross sections in terms of Legendre polynomials and by further comparison to model predictions. A new solution of the SAID partial-wave analysis obtained after adding the new data into the fit is presented.
