Modulated microwave absorption spectra associated with the intermediate state have been observed at 15.1 GHz for an oblong mercury sample. The use of a liquid-helium bath eliminated the thermal instabilities associated with modern, gas-flow cooling systems. Differences in the absorption signals observed with low modulation amplitudes, which depend on the direction of passage through the intermediate region, could be due to either the supercooling of the normal state below /ital H//sub /ital c// or the dependence of the domain topology on the thermodynamic path.
