摘要 Highly ionized Spectra from sulfur obtained at an energy of 80 MeV have been studied in the 19.0～53.0 nm wavelength range. Radiative lifetimes for some n =2 level in Be+-like S ⅩⅢwere measured using he beam-foil time of flight method. The results, using an arbitrarily normalized decay curves analysis, are compared with theoretical predictions and earlier measurement.
