Popis: | Thermal expansion of ${\mathrm{H}}_{2}\mathrm{O}$ and ${\mathrm{D}}_{2}\mathrm{O}$ ice Ih with relative resolution of 1 ppb is reported. A large transition in the thermal expansion coefficient at 101 K in ${\mathrm{H}}_{2}\mathrm{O}$ moves to 125 K in ${\mathrm{D}}_{2}\mathrm{O}$, revealing one of the largest-known isotope effects. Rotational oscillatory modes that couple poorly to phonons, i.e., lattice solitons, may be responsible. |
