Analysis of Zero-Point Isotherm of Hydrogen Isotopes in the Ultrahigh Pressure Range

We describe the experimental setup, as well as results and analysis of experiments on isothermal compression of stable hydrogen isotopes, viz., protium (H 2 ) and deuterium (D 2 ), in the initial (at P 0 = 0.1 MPa) solid state up to pressure of 550 GPa using facilities based on a magnetocumulative g...

Summary:We describe the experimental setup, as well as results and analysis of experiments on isothermal compression of stable hydrogen isotopes, viz., protium (H 2 ) and deuterium (D 2 ), in the initial (at P 0 = 0.1 MPa) solid state up to pressure of 550 GPa using facilities based on a magnetocumulative generator and an X-ray diffraction complex including a betatron and an X-ray image recording system. We consider the points obtained on the “cold” isentrope ( T 0 = 5–13 K) for protium and deuterium. The results are compared with those obtained using static and other dynamic facilities, as well as with the results of various calculations.
