Abstract : By exploiting the SAGE spectrometer a simultaneous measurement of conversion electrons and gamma rays emitted in the de-excitation of excited levels in the neutron-deficient nuclei Hg-184,Hg-186 was performed. The light Hg isotopes under investigation were produced using the 4n channels of the fusion-evaporation reactions of Ar-40 and Sm-148,Sm-150. The measured K- and L-conversion electron ratios confirmed the stretched E2 nature of several transitions of the yrast bands in Hg-184,Hg-186. Additional information on the E0 component of the 2(2)(+) -> 2(1)(+) transition in Hg-186 was obtained.
