This paper has systematically analysed the fast neutron scattering data for ~(6,7)Li by means of optical model method. The incidence energy being 4.83-15MeV and 7-15MeV for ~6Li and ~7Li respectively and the data analysed include total crossection, elastic crossection and angular distribution. The result obtained is in good agreement with the experimental data. The optical potential we use is of the Woods-Saxon type with surface absorption and spin-orbit coupling, We choose diffusion parameter of the real part and surface absorption depth as energy dependent parameters which vary with incidence energy linearly. All other parameters are independent of energy and besides, they are same for ~6Li and ~7Li, We discover that the diffusion parameter of the real part slowly decrcases with the increasing of insidence energy.

应用光学模型系统分析了~(6,7)Li的快中子散射资料,入射能量分别为4.83—15MeV(对~6Li)和7—15MeV(对~7Li),分析的资料包括总截面、弹性积分截面和角分布,所得结果与实验符合较好。所用的光学势为包含了面吸收和自旋轨道耦合项的Woods-Saxon型势。我们取实部(氵弥)散参数和面吸收深度为入射能量的线性函数,其它势参数均取为是能量无关的且对~6Li和~7Li还取为是一样的。发现实部(氵弥)散参数随入射能量增加而缓慢地减小。

A complex optical model potential modified by incorporating the concept of bonded atom, which takes into consideration the overlapping effect of electron clouds between two atoms in a molecule, is employed to calculate the absolute differential cross sections, the elastic integral cross sections, and the moment transfer cross sections for electron scattering from O_2 and CF_4 in the energy range 300—1000?eV by using additivity rule model at Roothaan-Hartree-Fock level. The quantitative absolute differential cross section, elastic integral cross section, and moment transfer cross section results are compared with those obtained by experiments and other calculations wherever available, and good agreement is obtained. It is shown that the additivity rule model together with the complex optical model potential modified by incorporating the concept of bonded atom can give better results than the one unmodified by it. So, the introduction of the bonded-atom concept in complex optical model potential betters the accuracy of the absolute differential cross sections, the elastic integral cross sections, and the moment transfer cross sections.

利用可加性规则,使用Roothaan-Hartree-Fock波函数,采用由束缚原子概念修正过的复光学势,在300—1000eV内若干个能量点处计算了电子被O2及CF4分子散射的微分截面、弹性积分截面及动量转移截面,并将计算结果与实验结果及其他理论计算结果进行了比较.比较的结果表明,利用被束缚原子概念修正过的复光学势及可加性规则进行计算,所得微分散射截面的精度要比利用未修正的复光学势及可加性规则进行计算得到的结果准确得多;同时,计算得到的弹性积分截面及动量转移截面也比较接近实验值.因此,在复光学势中采用束缚原子概念可提高电子被分子散射的微分截面、弹性积分截面及动量转移截面的计算准确度.
