3. Gshneider, K.A.: Solid State Phys.16, 276 (1964); here only room-temperature values of $$\bar \gamma$$ , ? and ? were given Full set of ?(T) experimental data though without $$\bar \gamma$$ (T) evaluation may be found in Touloukian, Y.S., Kirby, R.K., Taylor, R.E., Desai, P.D.: Thermal expansion: Metallic elements and alloys. New York: Plenum Press 1975
4. Experimental $$\bar \gamma$$ (T) data for Pd are given in Waterhouse, N., Yates, B.: Cryogenics8, 267 (1968).
5. Less detailed data may be found also in White, G.K., Pawlowicz, A.T.: J. Low Temp. Phys.2, 631 (1970) and in Ref. 18; all these data confirm the presence of low-temperature fall of $$\bar \gamma$$
