The superconducting-state heat capacity of Na0.3CoO2 was investigated. The results shows the presence of two distinctly different energy gaps and line nodes. The small gap contribution obtained in this way was very similar to one for Sr2ruO4. It was observed that the vortex-state data, showed strong fluctuation effects.
