New transport (resistivity versus temperature) and tunneling (low-temperature STM) measurements are reported on YNi2B2C samples prepared by inductive melting from the pure elements. Estimations of Debye temperature, electron-photon interaction parameter λ, plasma frequency and superconducting energy gap are given. Normal-state and superconducting data fit in a consistent picture of BCS superconductivity with λ ≤ 1.

Abstract
New transport (resistivity versus temperature) and tunneling (low-temperature STM) measurements are reported on YNi2B2C samples prepared by inductive melting from the pure elements. Estimations of Debye temperature, electron-photon interaction parameter λ, plasma frequency and superconducting energy gap are given. Normal-state and superconducting data fit in a consistent picture of BCS superconductivity with λ ≤ 1.
