                         in semiconductors is investigated further in order to calculate 
                         the specific heat of Si:P. The effect of correlation as well as 
                         overlap on the electron hopping energy integral is taken into 
                         account via Heitler-London two-particle wave functions. The 
                         calculated specific heat shows good agreement when compared to the 
                         experimental data over a wide range of impurity concentration 
                         around the criticai value for MNM transition. The comparison 
                         between MT and AMO-MT calculations shows a big enhancement due to 
                         electron correlation. The results of the 
                         highly-correlated-electron-gas model and inhomogeneity model are 
                         shown for the sake of comparion.",
