Abstract

Thermal expansion coefficients and specific heats are reported for orientationally disordered KBr samples containing CN concentrations ranging from 0.03 to 50 mol %, and within a temperature range of 0.08–10 K. With increasing CN concentration, a broad spectrum develops in the coupling parameter between the tunneling excitations and lattice strains. As with other properties reported previously, the thermal expansion for 50 mol % CN in KBr is similar to that of an amorphous solid.
