Laser-Enhanced Ionization Spectrometry of Atoms by the Laser Evaportions of Sample.

“…Excitation scheme of Aluminum has the following stages: Зр 2 P3/2 λ1 =396,l nm →3s 2 S1/2 λ2=555,7 nm 4p 2 P1/2 The two step scheme has not been described so far in references. At second step determination accuracy turned out to be 100 time bigger than it was obtained according to the known schemes described in [12]. In order to get maximurn effectiveness of atomization dependence value of aluminum signal on type of flame (acetylene-air, acetylene-nitrogen oxide) and proportions of burning gas and oxidant.…”

“…The many physical methods are used in the atomspectroscopy and laser analytical spectroscopy for In the results of study of this elements we exactly determined ionization limit, quantum defects, main quantum numbers, effective schemes of excitation, evaporation velocity, and disposition of effective Rydberg and autoionization states [1][2][3][4][5][6][7][8][9][10][11][12][13]. Investigation of Rydberg and autoionizing states of NaI and AlI are not only of significance in the atomic spectroscopy but also of great practical value in laser-analytical spectroscopy.…”

“…Moreover scientific investigation are carried out method of laser-enhanced ionization [LEI] spectroscopy or atom-ionization [AI] spectroscopy. Last time, investigation by the LEI was carried out in following atomizers: the flame atomizer in atmospheric pressure, rod-flame system, laser ablation of samples in flame, the electro thermal atomizer in the inert medium [8][9][10][11][12][13]. The high selectivity of the method gives possibilities of its application to analyze the objects of the complicated composition in the field of geology, medium.…”

“…Среди них наиболее перспективным и разработанным для практических применений являются лазерная резонансно-ионизационная спектроскопия (ЛРИС) в вакууме, атомноионизационная спектроскопия (АИС) в пламени, лазерная атомно-флуоресцентная спектроскопия (ЛАФС) и внутрирезонаторная лазерноабсорбционная спектроскопия (ВРЛАС). Каждая из них имеет свою преимущественную область применения [3,[16][17][18][19][20].…”
