Observation on Stark-Shifts of Lyman alpha Lines of Low-Z Ions in Laser-Produced Plasmas.

摘要

The red shifts have been observed for Lyman alpha lines of Be IV, B V, C VI and N VII at an electron density of 5 x 10 exp 21 cm exp -3 . The high density plasma was 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. (Atomindex citation 15:050981)
