摘要：

We have measured the lifetime and frequency of acoustic phonons in niobium by triple-axis neutron spectroscopy over a range of temperatures spanning the superconducting transition temperature, and have extracted quantitative information on the q and polarisation dependence of the electron-phonon interaction. The behaviour of the transverse modes supports a simple calculation based on the BCS theory of superconductivity, but the damping of a longitudinal mode appears to be unusually severe.
