4 the spectrum of highly ionized cu and ge was investigated by means of the beam - foil technique . by comparison with other experimental data we determined 42 energy levels of cu and 13 energy levels of ge . for the spectrum without experimental data for comparison , they are determined by isoelectronic sequence 摘要4我們采用束箔光譜方法測量高離化態cu和ge束的光譜線,與文獻中的實驗數據相對照,確定了42條cu的譜線和13條ge的譜線,對于無實驗值可對照的譜線,利用理論值和實驗值進行等電子序列證明。

The isoelectronic system of gap : n has been investigated extensively in the dilute limit since 1965 . thomas et al identified that a series of sharp emission lines in gap : n were due to the recombinations of excitons bound to either isolated nitrogen centers or various nitrogen pair centers 這些譜線來自于等電子雜質n形成的束縛激子態(孤立n中心和nn _ i對)輻射復合產生的零聲子線及其聲子伴線。

2 the experimental principle and method of beam - foil spectroscopy are presented , and the application of the isoelectronic sequence in the analyses of spectra is described , cowan program for the theoretical calculations is introduced 2介紹了束箔光譜學的實驗原理和方法,說明了等電子序列及其在譜線識別中的應用,介紹了用于理論計算的cowan程序。

In chapter 1 , the history investigation of gap : n with dilute nitrogen concentration , especially its isoelectronic exciton mechanics and the study background of gapn alloys are briefly introduced 早在二十世紀六十年代, thomas等人就發現在gap : n中,存在一系列尖銳譜線。
