[en] New data for the melting curve of He⁴ for temperatures between 4 and 25 K agree with earlier results by Mills and Grilly (Phys. Rev.; 99:480 (1955)) and by Crawford and Daniels (J. Chem. Phys.; 55:5651 (1971)), but disagree with the relationship given by Glassford and Smith (Cryogenics; 6:193 (1966) who carried out equation of state studies on fluid and solid He⁴. The reasons for the disagreement are not clear, but can be interpreted in terms of temperature scale inaccuracies which could have influenced all of their results. (author)
