The deviations between calculated and measured values of cohesive properties of alkali halides have motivated us to frame a model for calculating the same for rock salt structure alkali halides. The present approach shall include the effect of many body Coulombian, Born-Mayer type overlap repulsive and Van Der Waals (vdw) interactions in the framework of rigid shell model (R.S.M.). We hope that our results will show excellent agreement with measured cohesive energies for all the alkali halides. Further we will compare our result with atomization energy.
