1)
Ref. 10. Points above 2.5 K with errors less than 0.3%. Corrected to T58
.
2) Ref. 20. Smoothed data.
3) Ref. 17. Values of the "reduced time delay", defined in terms
of Whitney and Chase's value for u1 at 0 K, u1(0)=23830(13)
cm/s, have been converted to velocities using our value of u1(0)=23821
cm/s obtained from an equation of state (Brooks (24)). This point was
included in the data set. In the range 0.2 K < T < 1.1 K, the results
are frequency dependent with variations as great as 20 cm/s between velocities
measured at 1 MHz and 11.9 MHz.
4) Ref. 22. A constant 54 cm/s has been subtracted from the data to produce
absolute agreement with the data of Tam and Ahlers. About 6 mK above T,
the data show an anomaly in the temperature measurement due to the density
maximum (change of sign of the expansion coefficient which affects the
convective mechanism for thermal equilibrium).
5) Ref. 25. Simultaneously measured u1, u2, u4.
6) Ref. 26. Simultaneously measured u1, u2, u4.
7) References 27, 28 and 29 are more modern papers covering not only the
velocity of sound, but also attenuation and dispersion, topics not contained
in this compilation.
