摘要
基于相对论性核子-介子模型,导出了考虑σ、ω介子交换的离壳光学势虚部公式,并利用色散关系讨论了对实部的修正。这些结果可用于有效质量的计算和对光学势行为的分析。
Based on the relativistic nucleon-meson model, the imaginary parts of the off-energy-shell optical potential are derived by considering σ—and ω—meson exchange. The correction of the real part is also discussed with the dispersion relation. These results can be used in the calculation of the effective mass and the analysis of the behaviour of the optical potential.
