We report the results of inelastic electron tunneling spectroscopy (IETS) on the ab plane (c-axis tunneling) of a slightly underdoped twinned NdBa 2Cu3Ox single crystal (Tc 93.5 K) performed with a scanning tunneling microscope at T 4.2 K. In the energy derivative (d2I/dV2) of the differential conductivity curves having coherence peak, dip and hump structures, we observe a resonance peak at 242 meV. Here we discuss the possible origin of this inelastic scattering peak.
