摘要: We have measured the shift of He II 4685.7-A line at electron density ranging from 2.5 x 10/sup 17/ to 18.8 cm/sup -3/ and temperature between 8 10.5 eV. The plasma was produced in a Z-pinch discharge. Systematic red shifts linear are observed. experimental results agreement with best-fit curve earlier by Pittman Fleurier obtained lower densities temperatures.
