Experimentally Determined Branching Ratios for Transitions in ArII

Relative spectral response calibration of a spectrometer system for laser induced breakdown spectroscopy using the argon branching ratio method

“…Moreover, the branching ratios of the argon lines below 350 nm have been measured by at least three different groups and have very high agreement (within 3% in most cases) between the results obtained by the different groups. [10][11][12]15 These UV lines all have at least one line to link them to the visible range, in which the Ar-HCL results agree very well with the QTH lamp results. Finally, there is no effect caused by selfabsorption in the HCL (see below).…”

“…The principle of the BR method is well known and has been discussed in the literature. [11][12][13][14][15][16][17][18] The ratio of the transition probabilities of two lines originating from the same upper level denes the branching ratio, which should be equal to the ratio of the measured spectrally integrated intensities, when corrected for the different detector response at two different wavelengths. The simple equations below then hold (see, for example, ref.…”

Experimental branching fractions, transition probabilities, and oscillator strengths in Sn I

“…An emission spectrum between 443.7 and 448 nm is shown in Fig. 1, where the Sn I line wavelengths were calculated based on the energy level data from [11][12][13], and the Ar II lines are based on the data given by Hashiguchi and Hasikuni [14]. The 446.056 nm line of Sn I was superposed with an Ar II line, so the branching fraction measurement of the 57326.72 cm −1 level having this transition had to be abandoned.…”

“…Gorshkov and Verolainen investigated the lifetimes of the 5p6s 1 P 0 1 and 3 P 0 0;1;2 , 5p5d 3 D 0 1;2;3 , and 3 F 0 2;3 levels with the multichannel delayedcoincidence methods [3]. Very recently, by the time-resolved laser-induced fluorescence technique, the radiative lifetimes for even-parity levels including nine levels in the 5p7p configuration and 40 levels along the J 1 5pnp (n 10-13, 15-19), J 2 5pnp (n 10-13, 15-19, 27, 31, 32) and 5pnf (n 4, 5, [9][10][11][12][13][14][15][16][17][18][19]22, 23) Rydberg series in Sn I have been reported by Zhang et al [4] and Zhang et al [5], respectively.…”

Model of the cathode dark space in noble gas mixture discharges

“…The Monte Carlo simulation providing a flexible description of the particles' motion and different collision processes has been applied by several authors (Tran Ngoc An er al 1977, Boeuf and Marode 1982, Ohuchi and Kubota 1983, Hashiguchi and Hasikuni 1988, Yumoto er al 1991, Hashiguchi 1991, Jianfen Liu and Govinda Raju 1992, Date er al 1992 and this method was chosen for our modelling of the CDS in noble gas mixtures, as well.…”
