Asymmetry of hydrogen lines in plasmas utilizing a statistical description of ion-quadruple interaction in Mozer-Baranger limit

An experimental study on the asymmetry and the dip form of the H line profiles in microwave produced plasmas at atmospheric pressure

“…But it is possible to find some studies in which calculations and partial corrections on the current theories of the Stark broadening are carried out, where the asymmetry for some concrete profiles is obtained. We can highlight in this sense the works of S Djurovic et al [5], S Sörge et aland Günter [8], C Stehlé et al [11] and Halenka et al [12]. The improvement of these models is going on at the moment and new detailed experimental data might contribute to the further development of broadening models.…”

Path integral approach for Stark broadening of Lyman lines in hydrogen plasma

“…Using the distribution of the mean gradient of the field B s (F) as given by Halenka, [24] the energy shift becomes: Using the distribution of the mean gradient of the field B s (F) as given by Halenka, [24] the energy shift becomes:…”

Spectral Line Shapes of He I Line 3889 Å

“…For He I we adopt the cut-off parameter and close electron-radiator collisions term, evaluated according to the semiclassical estimation, see [16,23]. For non-hydrogenic radiator the ionic contribution to the self-energy is related to the quadratic Stark effect and quadrupole interaction [24], further details are given in [15,16]. The above procedure is used to describe the perturbing effect of free electrons on the radiator from the electronic self energy and the interference correction, which gives exactly the same expression as the semiclassical impact approximation of Griem [1], if the term with q 2 is neglected in the argument of delta function as in the classical limit, see Equation (4.5) in [13].…”
