| Abstract: | By the extended Huckel method incorporating special points procedure,and by use of the selfcontained subroutine,the densities of energy states of sodium halides crystals are calculated.The position of the valence levels,the band gaps and the widths of the valence bands are found by virtue of such method.This method is simple and effective,the calculated results coinside well with experimental data and some theoretical findings. |

| Keywords: | density of energy state energy gap width of valence band |
