Abstract	We propose to exploit the unique capability of ISOLDE to provide post-accelerated $^{220,222}$Rn and $^{222,224}$Ra ion beams from the REX facility to enable the Coulomb excitation of the first 3$^{-}$ states in these nuclei. By measuring the $\gamma$-ray yields of the E1 decays from the 3$^{-}$ state using the MINIBALL array we can obtain the <3$^{-}$ $\mid$E3$\mid$0$^{+}$> transition matrix elements. This will give quantitative information about octupole correlations in these nuclei. We require 22 shifts to fulfil the aims of the experiment.
