Lifetime Measurement for Some n=2 Levels in Be-like Sulfur
-
摘要: 主要报导用束箔技术对天体等离子体中重要元素硫的高电离态原子n =2的某些能级寿命的实验测量.实验数据用CANDY程序分析 ,并与理论计算结果和其它的实验结果作了比较. Lifetime measurement has been carried out for some low lying n=2 levels in the four electron ions S ⅩIII by using the beam-foil technique at National Laboratory of Heavy Ion Accelerator, Lanzhoiu, China. Spectra of highly ionized sulfur obtained at an energy of 2.5 MeV/nucleon have been studied in the 190-530 wavelength range. Experimental decay curves are analysized by the CANDY program, and compared with theoretical calculations and experimental measureaments.Abstract: Lifetime measurement has been carried out for some low lying n=2 levels in the four electron ions S ⅩIII by using the beam-foil technique at National Laboratory of Heavy Ion Accelerator, Lanzhoiu, China.
