Thermal Expansion of Single-Crystal H2O and D2O Ice Ih
Abstract
Thermal expansion of H2O and D2O ice Ih with relative resolution of 1 ppb is reported. A large transition in the thermal expansion coefficient at 101 K in H2O moves to 125 K in D2O , revealing one of the largest-known isotope effects. Rotational oscillatory modes that couple poorly to phonons, i.e., lattice solitons, may be responsible.
