动量空间中能质子-^(12)C弹性散射截面和自旋量的研究

A study of the cross sections and the spin observables for proton-^(12)C elastic scattering in momentum space in the intermediate energy region

在KMT理论框架下,应用微观的动量空间一级光学势,包括了库仑修正,自旋关联,NN振幅反对称,离壳效应,核子反冲和结合能转换,Lorentz不变的角变换.在整个中能区域系统地计算了质子-12C弹性散射微分截面和自旋观测量,并与实验数据及Glauber理论框架下或已有的其他理论计算结果做了比较,其结果显示,在200—1000MeV,该理论与实验结论符合程度较好.

The differential cross sections and the spin observables of p-^12C elastic scattering in the whole intermediate energy region are calculated using the KMT multiple scattering theory with microscopic momentum space optical potential which incorporates the spin dependence of the NN and p-^12C interactions. The theory takes into consideration the antisymmetrized NN amplitudes, nucleon recoil and binding energy shifts, Lorentz invariant angle transformations, t matrices with on-shell behavior from NN phase shifts, and off-sheU behavior from a realistic separable potential model. Qualitative agreement is found in differential cross sections and polarization data for 200 〈 Ep 〈 1000 MeV.
