Nuclear effects produce hyperfine structure . 原子核的影響引起超精細(xì)結(jié)構(gòu)。
The coherent excitation property of a two - level atom with a hyperfine structure in narrow band laser field 窄帶激光與能級(jí)具有超精細(xì)結(jié)構(gòu)的二能級(jí)原子的相干激發(fā)
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 介紹了研究原子能級(jí)超精細(xì)結(jié)構(gòu)的兩個(gè)實(shí)驗(yàn):磁共振實(shí)驗(yàn)、共線(xiàn)快離子束相互作用實(shí)驗(yàn)。
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 介紹了原子能級(jí)的精細(xì)結(jié)構(gòu)與超精細(xì)結(jié)構(gòu)的產(chǎn)生原理,對(duì)研究原子能級(jí)精細(xì)結(jié)構(gòu)的兩個(gè)實(shí)驗(yàn)作了改進(jìn)、設(shè)計(jì)及說(shuō)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.
