We report the low temperature specific heat of ternary iron-silicide superconductor Lu 2 Fe 3 Si 5 with T c = 6 K down to $T c /20. We find that a normalized specific heat jump at T c , DC/c n T c , is smaller than BCS value of 1.43. We also find that the specific heat divided by temperature C/T sho
## Abstract By expressing the free energy as an appropriate temperature integration over the square of the BCS energy gap function and by substituting simple but accurate analytic expressions for the latter, corresponding expressions are obtained for the specific heat in the superconducting state.
