Abstract
The thermal conductivity of the borocarbide superconductor LuNi2B2C (T-c = 16 K) was measured in the temperature range from 50 mK to 100 K. An unusual ly large phonon peak is observed in the superconducting state and the data at very low temperature is consistent with this material being an s-wave su perconductor.
