The interaction of nucleon-nucleon (NN) has certain physical characteristics, indicated by nucleon, and meson degrees of freedom. The main purpose of this work is calculating the ground-state energies of and through the two-body system with the exchange of mesons (, , and ) that mediated between two nucleons. This paper investigates the NN interaction based on the quasirelativistic decoupled Dirac equation and self-consistent Hartree-Fock formulation. We construct a one-boson exchange potential (OBEP) model, where each nucleon is treated as a Dirac particle and acts as a source of pseudoscalar, scalar, and vector fields. The potential in the present work is analytically derived with two static functions of meson, the single-particle energy-dependent (SPED) and generalized Yukawa (GY) functions; the parameters used in meson functions are just published ones (mass, coupling constant, and cutoff parameters). The theoretical results are compared to other theoretical models and their corresponding experimental data; one can see that the SPED function gives more satisfied agreement than the GY function in the case of the considered nuclei.

利用核子-核子相互作用的中子势计算某些核的基态

核子-核子(NN)的相互作用具有某些物理特征,由核子和介子自由度表示。这项工作的主要目的是计算的基态的能量和与介子的交换通过两个体系统( 在两个核子之间介导的 本文研究基于拟相对论解耦的Dirac方程和自洽Hartree-Fock公式的NN交互作用。我们构建一个单玻色子交换势(OBEP)模型,其中每个核子都被视为狄拉克粒子,并充当伪标量,标量和矢量场的来源。通过对介子的两个静态函数,单粒子能量相关(SPED)和广义汤川(GY)函数的分析,可以得出本工作的潜力。介子函数中使用的参数只是已发布的参数(质量,耦合常数和截止参数)。将理论结果与其他理论模型及其相应的实验数据进行比较;
