The temperature dependence of the London penetration depth, [Formula presented], was measured in both single crystal and polycrystalline [Formula presented] samples by a high-resolution, radio frequency technique. A clear exponential temperature dependence of [Formula presented] was observed at low temperature, indicating [Formula presented]-wave pairing. A BCS fit to the lowest temperature data gives an in-plane energy gap [Formula presented] of [Formula presented] [Formula presented], which is significantly smaller than the standard BCS weak coupling value of 3.5. We find that the data are best described by a two-gap model.
