Regularities in the Stark widths of spectral lines of ns - n′p and np - n′s transitions for a series of neutral atoms

Abstract

Dependencies enabling one to estimate the Stark widths of spectral lines due to s-p and p-s transitions of neutral atoms with an accuracy of about 30% are proposed. A simple parameter being a criterion of applicability of these dependencies is introduced. It is shown that these dependencies can be used to calculate the line widths of some heavy elements. © 2000 Elsevier Science B.V.
