Broadening of Spectral Lines

“…4). At small Γ, the results are quite consistent with the triple-recombination rate in ideal plasmas (6) where C = 1.5, i.e., within the limits C = 1-3 [11]. In the case of a high nonideality, the recombination rate turns out to be considerably lower than that predicted by formula (6), which is consistent with the results of [12].…”

“…It was considered that in the course of the relaxation, the temperature T e of free electrons and the plasma density remained invariable. The values of atomic constants and of collisional-transition rates were taken from [6,7].…”

Measurements of the parameters of a condensed deuterated Z-pinch on the angara-5-1 facility

“…This technique, described in [7], was used to determine Т ет by comparing the spectra obtained in our experiments with the spectra of nanosecond laser plasma with the wellknown electron temperature [11]. Preliminary estimates of the parameters of our plasma showed that its comparison with nanosecond laser plasma, which is well described by the coronal model, is quite correct [12]. The spectra were processed in accordance with the procedure described in [13].…”

Dielectronic recombination rate in statistical model

“…Thus, the DR rate calculations of its ions are significant for evaluation of its impurities. The detailed level-bylevel calculations of the DR rate dependence Qdr(T) on plasma temperature T for multielectron ions are a very difficult problem since for complex atoms like tungsten they require to take into account a huge number of atomic states and configurations [1]. The general expression for the DR rate represents itself the sum over branching ratios assembled from the total radiation ( ) …”

“…For the simplification of the calculations it is conventional to average (i, ; ) a W nl f over the orbital momentum l of the external electron [1,[4][5], that gives with the use of quasiclassical asymptotics the result (i, ;f)…”
