POLARIZABILITY DIELECTRIC CONSTANT PRESSURE AND DENSITY OF SOLID PARAHYDROGEN ON MELTING LINE

Polarizabilities, calculated from measurements of the dielectric constant, are reported for solid parahydrogen on the melting line between 18 and 320 atm (14.4°-22.2°K). Also new melting pressures below 17°K are presented. Previously reported solid densities are adjusted slightly, using the new resulting pressure data. Liquid parahydrogen polarizabilities were determined over part of the density range of the solid and are seen to be slightly less than the solid polarizabilities.
