| Abstract: | Two new parameters which take into account the effects of elastic anisotropy and phonon dispersion on lattice specific heat in the case of sodium and potassium have been evaluated. A new graded mesh method which uses a 162-direction approximation in (1/16) part of the Brillouin Zone (BZ) has been considered to evaluate the two parameters. |
| Keywords: | Dispersion parameter anisotropy parameters Brillouin zone graded mesh method Gaussian-quadrature formula specific heats |
