Calculation of the cohesive energy of solids with the use of valence electron structure parameters

This article describes a new calculation method for the cohesive energy of pure crystals by introducing the self-consistent bond length difference (SCBLD) into the empirical electron theory (EET) of solids and molecules. The computational accuracy of cohesive energy for 44 solids is evaluated in terms of a set of statistical quantities. The results show that the calculation method in the present paper can exhibit the excellent calculation accuracy in cohesive energy, demonstrated by the mean absolute relative errors (MARE in percent) of 2.34%.
