Observation on Stark-shifts of Lyman Alpha lines of low-Z ions in laser-produced plasmas
Abstract
The red shifts were observed for Lyman alpha lines of Be IV, B V, C VI, and N VII at an electron density of 5 x 10 to the 21st power cm(-3). The high density plasma ws produced by a 0.1 TW and 100 ps laser irradiation onto a plane target. The shift was measured by comparing the position of highly broadened line center with that of spatially resolved unperturbed one in a single shot photograph. The results are compared with simple theoretical estimations.
