Abstract
Experiments carried out at high pressures show that the transition of completely ordered solid N2 to orientationally disordered -N2 is shifted over a factor of 2 in temperature or pressure due to the admixture of fluid helium. Between 5.4 and 11.0 mole % helium can be dissolved in favoring the occurrence of this ordered phase. In contrast, the transition from disordered to disordered N2 is not shifted at all.
