Abstract
We present a study of the anisotropy in the superconducting energy gap in a single crystal of YNi2B2C (Tc~14.6 K) using directional point-contact spectroscopy. The superconducting energy gap at 2.7 K, when measured for I||c, is 4.5 times larger than that for I||a. The energy gaps in the two directions also have different temperature dependences. Our results support a scenario with s+g like symmetry.
