- We investigate mixed (50/50) clusters of parahydrogen and orthodeuterium at low temperature, by means of Quantum Monte Carlo simulations. Our results provide evidence of liquid-like behavior and partial isotopic separation in a cluster of 640 molecules, at temperature T=10 K. As the temperature is lowered below ~ 6 K, crystallization occurs, with no indication that the liquid phase is more resilient at low temperature in a mixed cluster. Isotopic separation is therefore predicted to take place at low temperature only through the slow process of molecular self-diffusion in a crystalline matrix.
