摘要：

Neutron scattering measurements on single crystals of hexagonal tungsten bronzes M0.33 WO3 reveal low-frequency, relatively dispersionless phonon branches which can be associated with the vibrations of the metal atoms M in the large open channels they occupy in the crystal structure. An analysis based on Eliashberg theory shows that the strong dependence of the superconducting transition temperature on the species M arises from these special phonons. © 1979 The American Physical Society.
