在光子束能量范围和极角范围内测量了反应的微分截面和光子束不对称性。在SPring-8 LEPS 2/BGOegg实验中用大接受电磁量能器进行了测量。在宽极角范围内的光子束非对称性的结果是新的光子束能量超过。现有的分波分析模型都没有描述在高能区观察到的不对称性。在这些能量下,轨道角动量为5的多极振幅的贡献被发现是重要的。
Differential cross sections and photon beam asymmetries for the reactionhave been measured in the photon beam energy range ofand thepolar angle range of. The measurement has been done by using a large acceptance electromagnetic calorimeter in the SPring-8 LEPS2/BGOegg experiment. The results of the photon beam asymmetry in a widepolar angle range are new for the photon beam energies exceeding. None of the existing partial wave analysis models describe the observed asymmetries in the high energy region. The contribution of multipole amplitudes with an orbital angular momentum of 5 in thesystem has been found to be important at these energies.
