isoscalar meaning in Chinese
同位旋标量
Examples
- Using the fully consistent rrpa method , we have studied the properties of collective multipole excitations for several closed - shell and closed sub - shell nucleus in the isoscalar modes and isovector modes
计算结果显示，从fermi海核子态到dirac海负能核子态形成的对激发在核的集体激发中的贡献很重要，尤其是对核的同位旋标量激发模式。 - 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 indicate that the effects of the dirac sea states are pronounced in the collective multipole excitations for nuclei , especially on the isoscalar giant modes , but become weaker for light nuclei , while the contributions on the isovector modes are negligible
在核的同位旋标量激发模式中， dirac海负能核子态在不同的共振模式中的贡献程度不一。对于同一种激发模式， dirac海负能核子态的贡献随着核子数的减少而变弱。 - The effective coupling constants including isoscalar and mesons and isovector and mesons in the rmf are extracted from the dbhf results in symmetric and asymmetric nuclear matter . two sets of effective interactions in the rmf approach are deduced by imposing a condition , where the dbhf scalar and . vector self - energy or scalar self - energy and binding energy per nucleon at each density and asymmetry parameter are reproduced , respectively
为了使我们提取的有效相互作用能够准确地再现出dbhf计算的核状态方程以及密度依赖的不对称能，我们采用第二种万法提取有效介子核子耦合常数，即要求在对称核物质中，每个密度处ilif计算出的标量自能及总结合能与dbhf给出的标量自能及总结合能一致，提取出。
