“…A modified version of the linear low pressure pulsed arc [5,10,[12][13][14][15][16][17] has been used as an optically thin plasma source. A pulsed discharge was driven in a Pyrex discharge tube of 5 mm inner diameter and plasma length of 7.2 cm.…”

Abstract. On the basis of the relative line intensity ratio (RLIR) method, transition probability values of the spontaneous emission (Einstein's A values) of 14 transitions in the singly (Kr II) and 7 transitions in doubly (Kr III) ionized krypton spectra have been obtained relatively to the reference A values related to the 435.548 nm Kr II and 324.569 nm Kr III, the most intensive transitions in the Kr II and Kr III spectra. Our Kr III transition probability values are the first data obtained experimentally using the RLIR method. A linear, low-pressure, pulsed arc operated in krypton discharge was used as an optically thin plasma source at a 17 000 K electron temperature and 1.65 × 10 23 m −3 electron density. Our experimental relative A values are compared with previous experimental and theoretical data.

“…Neon also occurs in supernovae ejecta (Thieleman et al 1986). After the earlier investigation of Ne ii Stark shifts (Pretty 1931;Maissel 1959;Mandel'shtam 1962;Mandel'shtam et al 1963;Mazing & Vrublevskaya 1962) the first measurements of d values at convenient plasma parameters (T and N ) were performed in only one experiment (Purić et al 1987). In this experiment (Purić et al 1987) d values of 18 Ne ii spectral lines from 13 multiplets were measured at 35 000 K electron temperature and 1.42 × 10 23 m −3 electron density.…”

Abstract. Stark shifts (d) and transition probabilities of the spontaneous emission (Einstein's A values) of forty two singly charged neon (Ne ii) ion spectral lines have been measured in a linear, low pressure, pulsed arc at 35 300 K electron temperature and 1.83 × 10 23 m −3 electron density. Transition probabilities have been obtained using the relative line intensity ratio (RLIR) method. Stark shift values have also been calculated, using the semiclassical perturbation formalism (SCPF). The measured and calculated shift values and the measured A values have been compared to the existing data taken from available data sources.

“…resonances or off-resonances; Puric, Cuk & Lakicevic 1985); multiplets, supermultiplets, spectral series and transition array within one stage of ionization (Z c 5 constant), or within several stages of ionization (Z c 6 ¼ const; Puric et al 1991;Puric et al 1993;Puric & Š cepanovic 1999;Puric et al 2008); (ii) within particular isoelectronic sequences (Puric et al 1988a); and (iii) within a given isonuclear sequence (Puric et al 1988b). In the case of a particular transition within a given homologous group of atoms or ions, it is more convenient to use a slightly different relation as the function of the nuclear charge number Z of the emitter (Puric et al 1987).…”

“…Both variables take into account the density of states perturbing the emitting state. However, some advantages of the present method are: (i) x-based trend analyses achieve better fits (compared to those obtained when integer quantum number is used instead; Puric et al 1987); (ii) using x-values, the lowering of the ionization potential (Inglis & Teller 1939) can be taken into account, predicting merging with continuum when the plasma environment causes the line's upper-state ionization potential to approach zero; and (iii) the dependence of the Stark width (w) on x is theoretically expected (Puric et al 1993;Puric et al 2008).…”

Abstract:The dependences of Stark width on the upper-level ionization potential within different series of the neutral beryllium spectral lines have been studied. The dependences previously observed for electron impact contribution to the Stark widths were also obtained for the proton impact contribution. The emphasis is on the fine structure influence on the studied Stark parameter dependences. The influence of temperature on the dependences of Stark width parameters has been demonstrated. The relations found can be used in both cases for prediction of new Stark broadening data, thus avoiding much more complicated procedures.
