标量介子 meaning in Chinese

scalar meson

In this paper , which is about p + a p " + a " + reaction process , exciting the n * ( 1440 ) in the projectile of protron mediated by an isoscalar ( cr ) exchange , we continued to work in the framework of effective theory
本文在以标量介子作为交换介子的有效理论框架下，在完全相对论的基础上，研究了p + a p + a +反应模型中，在入射粒子p上产生共振激发态n ~ * ( 1440 )的反应过程。
The results show that binding energies per nucleon at each density and various asymmetry parameters fulfill the empirical parabolic law and the asymmetry energy is density dependent . it is found that both scalar and vector potentials of neutron in the neutron rich nuclear matter become stronger although the isospin dependence is not stronger . we compare our results with those in a simple method , where the dbhf nucleon self - energies are extracted from the momentum dependence of the single - particle energy
首先我们要求在每一个密度及各种不对称系数的核物质中，相对论平均场（ rmf ）计算出的核子标量与矢量自能与dbhf计算出的标量与矢量自能一致，从而得到在rmf下的密度依赖的有效介子核子耦合常数，包括同位旋标量介子。
