Abstract

Recent investigation at our institute revealed that the solid-fluid-fluid three-phase line of the system helium-nitrogen shows two quadruple points in the pressure range up to 10 GPa. Since each quadruple point is connected with four three-phase lines, the phase diagram is very complicated. We have detected the phase transitions representing solid-solid-fluid equilibria. Moreover, two lines of constant composition have been determined as a function of temperature and pressure. These results are discussed together with the implications for the phase diagram of both He-N2 and pure nitrogen.
