Nuclear effects produce hyperfine structure . 原子核的影响引起超精细结构。
The coherent excitation property of a two - level atom with a hyperfine structure in narrow band laser field 窄带激光与能级具有超精细结构的二能级原子的相干激发
It follows that two experiments of hyperfine structure of atomic energy level which are called magnetic resonamce experiment and co - line expression beam interative experiment 介绍了研究原子能级超精细结构的两个实验:磁共振实验、共线快离子束相互作用实验。
This article is aimed at introducing the generation principle of fine structure and hyperfine structure of atomic energy level , with its experimental result improved , designed and illustrated 介绍了原子能级的精细结构与超精细结构的产生原理,对研究原子能级精细结构的两个实验作了改进、设计及说明。
The term hyperfine structure refers to a collection of different effects leading to small shifts and splittings in the energy levels of atoms, molecules and ions. The name is a reference to the fine structure which results from the interaction between the magnetic moments associated with electron spin and the electrons' orbital angular momentum.
