In order to study the gap function of the newly discovered skutterudite superconductor PrPt4Ge12(Tc=7.9K),we have measured the London penetration depth λ(T) and specific heat of the single crystalline PrPt4Ge12 down to 0.05Tc.The temperature dependence of Δλ below 0.3Tc follows a power low of Δλ∝Tn,where n is between 2.7 and 3 for different samples.
