Abstract

We report here two kinds of time-of-flight inelastic-neutron-scattering measurements using LAM-D and LAM-40 spectrometers on an aggregate of randomly oriented single crystals and a piece of single crystal, respectively, of hydrogenated κ-(h₈-BEDT-TTF)₂ Cu(NCS)₂. The generalized partial density-of-states spectrum shows an anomalous enhancement in low-lying energy regime below several meV at low temperatures below T_c. It suggests that low-lying vibrational modes involving protons at terminal ethylenes appear in the superconducting phase.
