Based on the group - theoretical structure for the density - dependent multi - photon jaynes - cummings model , we have constructed the dressed su ( 2 ) coherent state . the atom and field squeezing and the anti - bunching effect for the system evolving from the dressed su ( 2 ) coherent state have been studied . in conclusion , we have discovered some new field and atomic squeezing in different systems , proposed a new kind of quantum state and discussed photon anti - bunching effect , sub - poissonian statistics distribution 5 .基于密度相關的多光子j那mes一c ~ gs模型的群結構,定義了密度相關的多光子jaynes一c ~ gs模型的修飾su ( 2 )相干態,并研究了系統以修飾su ( 2 )相干態作為初態的原子和光場的壓縮,光子的反聚束等效應。
In chapter five , the rempi - tof - ms of methanol are investigated in the range of 279 . 5 - 286 . 5nm . the main results are : ( 1 ) the tof - ms and rempi spectrum of methanol are measured . ( 2 ) the tof - ms of methanol is identified ; the rempi spectrum of c , ch3 and ch2o are analyzed 第五章主要報道了甲醇分子在279 . 5一286 . 5nm范圍內的共振增強多光子解離一電離過程的實驗研究結果和分析結果,主要內容有: ( 1 )實驗測定了甲醇分子的共振增強多光子電離的tof質譜和分質量的rempi譜。
( 2 ) the tof - ms of acetaldehyde is identified ; the rempi spectra of c , ch , and ch3 are analyzed . ( 3 ) the possible mechanism of dissociation / ionization is analyzed , ( 4 ) it is also proposed that the main dissociation channel is non - resonant photodissociation of parent molecule followed by the further photodissociation or photoionization of the fragments ( 3 )通過對實驗測定的tof質譜和分質量的rempi一譜的分析,討論了乙醛分子的多光子共振解離一電離通道以及碎片的解離通道,分析結果表明乙醛分子的主要解離通道是該分子先多光子解離,然后是解離碎片的進一步解離或多光子電離。
