利用新研制的极化质子固体靶，在0.09 t的低磁场下，首次测量了71 MeV/核子下质子弹性散射的矢量分析能力，结果与a-矩阵折叠模型预测结果不相容。与矩阵折叠分析数据的比较表明，向量分析能力对反应分析中使用的核结构模型很敏感。认为核芯分布可能是理解核结构敏感性的关键。
Vector analyzing power for the proton-elastic scattering at 71 MeV/nucleon has been measured for the first time, with a newly developed polarized proton solid target, which works at a low magnetic field of 0.09 T. The results are found to be incompatible with a-matrix folding model prediction. Comparisons of the data with-matrix folding analyses clearly show that the vector analyzing power is sensitive to the nuclear structure model used in the reaction analysis. The-core distribution inis suggested to be a possible key for understanding the nuclear structure sensitivity.
