摘要

我们用微观耦合通道(MCC)计算质子弹性散射和非弹性散射。对角线势和耦合势包括自旋轨道部分,是通过折叠具有跃迁密度的复G矩阵有效核子-核子相互作用得到的。这是首次将自旋轨道部分的折叠公式应用于质子非弹性散射。我们将MCC计算分别应用于$^{12}$C靶在$E_p$ = 65和$ 200mev下的质子弹性和非弹性(0$^+_2$)散射。对角线势和耦合势对中心和自旋轨道部分的作用进行了检验。此外,利用修正波函数和修正跃迁密度分别研究了跃迁密度与质子非弹性散射的关系。非弹性截面对过渡密度的强度和形状敏感,但非弹性分析能力只对过渡密度的形状敏感。最后,明确了由跃迁密度导出的非弹性分析功率的性质,没有歧义。

Relation between transition density and proton inelastic scattering by C12 target at Ep=65 and 200 MeV
We calculate proton elastic and inelastic scatterings with a microscopic coupled channel (MCC) calculation. The diagonal and coupling potentials including the spin-orbit part are obtained by folding a complex $G$-matrix effective nucleon-nucleon interaction with a transition density. This is the first time that the present folding prescription for the spin-orbit part is applied to the proton inelastic scattering. We apply the MCC calculation to the proton elastic and inelastic (0$^+_2$) scatterings by $^{12}$C target at $E_p$ = 65 and 200 MeV, respectively. The role of diagonal and coupling potentials for the central and spin-orbit parts is checked. In addition, the relation between the transition density and the proton inelastic scattering is investigated with the modified wave function and the modified transition density, respectively. The inelastic cross section is sensitive to the strength and shape of the transition density, but the inelastic analyzing power is sensitive only to the shape of that. Finally, we make clear the property of the inelastic analyzing power derived from the transition density without an ambiguity.
