Lifetime Measurements for some Δn= 0 Transitions in Cl XIII-Cl XV

Abstract
A beam-foil investigation of chlorine at energies up to 48 MeV has been performed in the wavelength region 300-1100 Å. Hydrogen-like transitions, as well as Δn = 0 transitions, belonging to Cl XII-Cl XV were observed. Radiative lifetimes and f-values are reported for some important Δn = 0 transitions, 2s 2S1/2-2p 2P3/2 and 2s 2S1/2-2p 2P1/2 in Cl XV, 2s2p 1P1-2p2 1D2 in Cl XIV and 2s2p2 2P3/2-2p3 2D5/2 in Cl XIII.
