Electron correlation effects in hyperpolarizabilities of squarates 二酮衍生物分子的超極化率和電子相關(guān)效應(yīng)
Bfs sensitively probes inter - electron correlation , relativistic and quantum electrodynamics corrections , so it can be used to test the basic many - body atomic theory or interpret spectra from space . the main contents of this dissertation are as follows : 1 the history and development of beam - foil spectroscopy are reviewed , and the characteristics of bfs are also described . the main applications in the spectroscopic studies and lifetime measurement of highly ionized ions are summarized 本文對高離化態(tài)cu和ge離子的光譜進(jìn)行實(shí)驗(yàn)研究,得到了一些新的實(shí)驗(yàn)結(jié)果,論文的主要內(nèi)容如下: 1回顧了束箔光譜法的發(fā)展歷史,介紹了束箔光譜法的優(yōu)點(diǎn);總結(jié)了束箔光譜法在高離化態(tài)原子能級(jí)研究,高離化態(tài)原子能級(jí)壽命測量等方面的主要用途。
Using the multi - configuration dirac - fock method ( mcdf ) , we studied the characteristic of the decay processes of the 4d core excited states of csiv , the low - lying excitation structure of super - heavy element bohrium ( z = 107 ) and the x - ray spectra of the 3d - 4f transitions of highly charged xenon ions in details in this work , by including the electron correlation and the relaxation effects systematically 本論文運(yùn)用mcdf方法,通過系統(tǒng)考慮電子相關(guān)效應(yīng)和馳豫效應(yīng),分別研究了cs離子的4d內(nèi)殼層激發(fā)態(tài)衰變動(dòng)力學(xué)特性,超重元素bh ( z = 107 )的低激發(fā)態(tài)結(jié)構(gòu)以及高離化態(tài)氙離子的3d - 4f躍遷產(chǎn)生的x射線譜的結(jié)構(gòu)等問題。
