PHENOMENA ALONG THE hcp-bcc TRANSITION LINE OF He$sup 3$ AND He$sup 4$
Journal Article

· Phys. Rev. Letters
The behavior of the Debye temperature along the crystal phase transition line and along the melting point curve of He/sup 3/ and He/sup 4/ is investigated to obtain information on the hexagonal -close -packed to body-centered-cubic transition (hcp to bcc). The solid phase transition occurs at the point of inflection of the potential energy vs nearest neighbor distance curve. In the bcc phase the force constant is governed predominantly by the zero-point repulsion plus some attraction, whereas in the hcp phase it is governed mostly by the zero-point repulsion. (C. E.S.)
