Determination of Debye temperature THETAsub(inf.) and anharmonic component of thermal conductivity for scandium, ittrium and lanthanum

Experimental data on specific heat capacity of scandium, yttrium and lanthanium at a temperature ranged from 4 to 300 K are reported. The Debye temperature in the high-temperature limit and the anharmonic heat capacity component at a constant volume of the test metals are calculated
