中文摘要：
在微观多体Brueckner—Hartree—Fock理论框架内，实现了三体核力对核物质中单核子势的重排贡献的计算，研究了三体核力重排贡献对单核子平均势场的动量相关性和密度依赖性的影响．另外，还计算了核物质中核子的有效质量并着重讨论了三体核力重排效应的影响．结果表明：三体核力对单核子势的重排贡献具有排斥性，而且三体核力的重排效应随动量和密度的增加而迅速增强：在高密度和高动量区域这一排斥贡献具有很强的动量相关性并起到了减弱单核子势吸引性和增强单核子势动量相关性的重要作用，有助于澄清非相对论性BHF平均势场在高密度和高动量区域吸弓l性过强和动量相关性过弱的问题．
英文摘要：
Within the framework of microscopic Brueckner-Hatree-Fock, the contribution of the three-body force （TBF） rearrangement to the single nucleon potential is calculated. The TBF rearrangement effects on the momentum and the density dependence of the single nucleon potential are investigated. The influence of the TBF rearrangement on the effective mass of nucleon is also discussed. It is shown that the rearrangement contribution of TBF is repulsive and momentum-dependent. The TBF rearrangement effect and its momentum dependence increase rapidly as increasing density and momentum. At high densities and high momenta, the repulsive rearrangement contribution reduces strongly the attraction of the single nucleon potential and enhances considerably the momentum dependence of the single nucleon potential.
