| 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. 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. |
