Abstract: | Acoustic phonon damping in Nb due to superconductivity is accurately measured by the inelastic neutron scattering technique. The phonon line widths can be characterized by the reduced parameters and T/Tc, and are in good qualitative agreement with the calculation by Bobetic based on the BCS theory. |
