Abstract

He embedded in a porous glass has been studied by neutron diffraction. Along the isochoric path studied, about 30% of the pore filling solidify in the bcc structure at 1.7 K and remain in this state down to 60 mK, the minimum temperature of the experiment. The other part of the pore filling is either liquid or an amorphous solid. The behaviour is discussed in terms of a thermodynamic model.
