本文给出了在50、65、70和100 MeV下He与极化He靶弹性散射的He分析本领的精确测量。在65和70 MeV的数据进行了比较与基于现代核子-核子势的理论预测。在theHe分析功率取最小值和最大值的角度处，可以清楚地看到数据和预测之间的巨大差异，这不能用等压线效应来解释。
We present a precise measurement ofHe analyzing powers forp-He elastic scattering with the polarizedHe target at 50, 65, 70, and 100 MeV. The data at 65 and 70 MeV are compared with the theoretical predictions based on the modern nucleon-nucleon potentials. Large discrepancies between the data and the predictions are clearly seen at the angles where theHe analyzing power takes the minimum and maximum values, which are not explained by-isobar effects.
