Title Absence of a low-temperature anomaly in the Debye-Waller factor of solid 4He down to 140 mK
Abstract The mean-square atomic displacement in hcp-phase solid 4He has been measured in crystals with a molar volume of 21.3 cm^3. It is temperature independent from 1 K to 140 mK, with no evidence for an anomaly in the vicinity of the proposed supersolid transition. The mean-square displacement is different for in-plane motions (0.122±0.001 Å^2) and out-of-plane motions (0.150±0.001 Å^2).
