Title: | Experimental transition probabilities in the Ar III and Ar IV UV spectra | Authors: | Burger, Miloš Skočić, Miloš Gavrilov, Momčilo Bukvić, Srđan Djeniže, Stevan |
Keywords: | Atomic transition probability;Emission spectroscopy;Line intensity | Issue Date: | 1-Sep-2012 | Journal: | Journal of Quantitative Spectroscopy and Radiative Transfer | Abstract: | We present transition probabilities (Einstein's A values) for 38 Ar III (doubly ionized argon) and 14 Ar IV (triply ionized argon) spectral lines from the wavelength interval 240-308. nm. Considered spectral lines are recorded in laboratory pulsed discharge. The relative line intensity ratio procedure has been applied in evaluation of transition probabilities. As a reference for transition probability evaluation we have chosen A value of 241.884. nm spectral line in Ar III spectrum and A value of 280.947. nm in Ar IV spectrum, both obtained theoretically. Careful analysis of experimental and existing theoretical data is conducted in order to deduce uncertainties. Presented Ar III and Ar IV A values are for the first time obtained relying on experimental data. © 2012 Elsevier Ltd. |
