Abstract
Anomalously high values of the superconductive transition temperature are correlated with anomalies in bond lengths in intermetallic compounds. The bond length anomalies arise from anharmonic stabilization of harmonic lattice instabilities, and confirm this interpretation of recent neutron studies of short-wavelength vibrational anomalies.
