11B(α,α)11B 反应的绝对横截面和角度分布的测量是在 11B(p,α) 研究中在 0.15 至 3.8 MeV 范围内进行的,在 11B(α,α) 反应中在 2 至 5.4 MeV 范围内进行的。绝对横截面以检测到的 α 粒子总数表示,以避免由于特定能量下反应中发射的 α 粒子数量的模糊性而导致的不确定性。 11B(p,α)8Be(2+) 反应的角分布符合勒让德多项式展开式并给出了系数。最后,11B(α,α)11B 数据根据相移进行拟合(忽略目标的自旋),提供 2 至 5.4 MeV 之间弹性截面数据的方便表示。
Measurements of the absolute cross section and angular distributions for theand the11B(α,α)11B reactions have been performed from 0.15 to 3.8 MeV for the11B(p,α) study and from 2 to 5.4 MeV for the11B(α,α) reaction. The absolute cross sections are presented in terms of the total number of α-particles detected in order to avoid uncertainties due to ambiguities in the number of alpha particles emitted in the reaction at a particular energy. The angular distributions of the11B(p,α)8Be(2+) reaction were fit to a Legendre polynomial expansion and the coefficients are presented. Finally, the11B(α,α)11B data were fit in terms of phase shifts (ignoring the spin of the target), providing a convenient representation of the elastic cross section data between 2 and 5.4 MeV.
