Abstract
The pressure dependence ofT c of uranium can be probably most simply understood in terms of pressure-induced phonon softening at short-wavelength. This interpretation of Smith and Fisher's data leads to a new proposal for the low temperatureP — T phase diagram. The so-calledα/α 1 phase boundary is expected to terminate in a critical point not unlike theγ/α phase line in cerium.
