We propose to observe three supernova remnants in the Magellanic clouds, i.e.DEM L 71, IKT 6 & IKT 23. The RGS spectra will allow us to study the emissionlines from single ions. In particular, the Helike series of O & Ne (in the caseof IKT 23) show peculiar ratios. The study of the Helike ratios will enable usto investigate largely unaccounted for phenomena, such as resonance scattering,recombination and charge transfer which affects line shapes and production.
