Second Sound in Solid Helium
Abstract
An experiment on temperature pulse propagation in a bcc crystal of $^{3}\mathrm{He}$ grown at 95.9 atm shows the existence of second sound in the solid below about 0.58\ifmmode^\circ\else\textdegree\fi{}K. In the temperature range $0.42\ifmmode^\circ\else\textdegree\fi{}\mathrm{K}lTl0.58\ifmmode^\circ\else\textdegree\fi{}\mathrm{K}$, reflections of the received pulses were observed. In the range $0.58\ifmmode^\circ\else\textdegree\fi{}\mathrm{K}lTl1.2\ifmmode^\circ\else\textdegree\fi{}\mathrm{K}$, the temperature pulses were observed to propagate diffusively.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
