Title: Revisiting the Stark Width and Shift of He II Pα

Abstract

We report experimental determination of plasma-induced Stark widths and shifts of the He II P α line and a comparison of the results with calculations performed by several computational approaches. The measurements were carried out in a small compressing plasma channel device, reaching electron densities in excess of 10¹⁸ cm^–3 and temperatures of a few eV. The experimental data are in a good agreement with some previously published studies. However, the measured relation between the Stark shift and width could not be reproduced by either of the codes, and this disagreement is not yet resolved. Furthermore this suggests the existence of an additional effect that is not accounted for in the present models and leads to a larger than expected Stark shift of the He II P α line.

Experimental Stark widths and shifts and transition probabilities of several Xe II lines

Journal Article Gigosos, M A ; Mar, S ; Perez, C ; ... - Physical Review. E, Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics; (United States)

This work reports measured Stark widths and shifts, and transition probabilities for a large nubmer of Xe II spectral lines. A pulsed arc was used as a plasma source. The electron density, determined by interferometry at one wavelength, and simultaneously by the Stark broadening of the 5016-A He I line, covers a range of (0.2--1.8)[times]10[sup 23] m[sup [minus]3]. A method is proposed to find simultaneously the plasma temperature and the transition probabilities from relative intensity measurements of spectral lines. Electron temperatures are in the range of 11 000--16 000 K. The measured parameters are compared with experimental data taken frommore » the literature.« less

Influence of ion dynamics on the width and shift of isolated He I lines in plasmas. II

Stark widths and shifts of the He I 7065-, 6678-, 5016-, 4713-, and 3188-A lines are measured in hydrogen-helium plasma. A repetitively pulsed low-pressure arc is used as a plasma source, while the signal averaging technique is employed to record the line profiles. The electron densities in the range of (2.5--5.9){times}10{sup 15} cm{sup {minus}3} are measured by 10.6-{mu}m laser interferometry. The electron temperatures ranging from 19 300 to 23 600 K are determined from the ratio of the H{sub {gamma}} line intensity to the underlying continuum, while the gas temperatures from 5000 to 12 600 K are measured from themore »« less

Line radiation was observed from a homogeneous and optically thin core region of the pinch discharge, free of impurity elements that could distort the line shape. The experimental shifts vary linearly with electron density and are in good agreement with calculations that we have performed on the basis of the classical-path and impact approximations for electron perturbers, according tomore »« less
