Radiative lifetimes and oscillator strengths for allowed intra-L-shell transitions in multiply charged chlorine ions

A systematic study of radiative lifetimes of low-lying levels in Clxv through ClIx has been made using the beam-foil time-of-flight techniques. These results are used to derive $f$ values for allowed $\Delta n=0\mathrm{}$ transitions of the type $2s^{2}2p^k-2s2\mathrm{}{p}^{k+1\mathrm{}}$ and $2s2p^{k+1\mathrm{}}-2\mathrm{}{p}^{k+2\mathrm{}}$.
