摘要

从相对论平均场理论出发，导出了ρ介子与核子的耦合参数gρ与饱和核物质密度ρ0、对称能量系数asym及核子有效质量m*之间的代数关系式；由得到的公式对相对论平均场理论计算中曾用到的几组ρ介子耦合参数进行了分析。采用NSCL/MSU给出的核子最新实验数据，对ρ介子与核子的耦合参数gρ进行了计算并做了初步讨论。

Abstract

The algebraic equation of gρis derived from the relativistic mean field theory. Several sets of ρ meson coupling constants used in RMF are analyzed. Adopting the new experimental data of NSCL/MSU

the coupling constants of ρ mesons are calculated.
