Abstract
We report on the determination of the electronic heat capacity of a slightly overdoped single crystal with a of 21.4 K. Our analysis of the temperature dependence of the superconducting-state specific heat provides strong evidence for a two-band -wave order parameter with gap amplitudes and .
