S. Glenzer et al., STARK-BROADENING OF SPECTRAL-LINES ALONG THE ISOELECTRONIC SEQUENCE OF B, Journal of physics. B, Atomic molecular and optical physics, 27(3), 1994, pp. 413-422
A systematic study of experimental Stark widths of 3s-3p and 3p-3d tra
nsitions in N III-Ne VI measured in a plasma produced by the gas-liner
pinch device is reported. The scaling of measured Stark widths with t
he spectroscopic charge number Z (Z = 3 for N III, etc) shows apprecia
ble deviations from that predicted by some theoretical calculations in
the electron-impact approximation A strong indication is found that p
roton collisions influence the linewidth of the 2s2p3s P-4(o)-2s2p3p 4
D transition in Ne VI in a significant way.
