A new device for the detection of evaporation residues in coincidence with y rays in heavy-ion induced reactions is presented. This new detector mainly discriminates against fission and allows Doppler corrections of the y spectra. As a first application, the level schemes of the neutron deficient lead isotopes 188Pb and 186Pb have been studied for the first time at the VICKSI accelerator. Both nuclei exhibit a structure different from heavier even-even Pb isotopes and show low-lying rotational bands.
