Abstract
An exchange‐correlation potential model to be used in connection with the multiple scattering method is presented. Retaining the main advantages of the multiple scattering method with the __X__α potential, particularly its low computational requirements, this new formalism does not require any adjustable parameter. Test calculations on the NiF~6~^4−^ system are reported and compared with experimental and ab initio results.

This article describes the numerical application of projection operators to restore the symmetry of molecular orbitals in self-consistent field (SCF) calculations when the symmetry is lost because of degeneracy or near degeneracy. The application of projection operators is particularly useful in cas
The paper presents a new calculation method for steady-state stagewise mass and heat transfer operations. The method is restricted to linear equilibrium relationships. The ideal stage model used is a new one and equations obtained are quite simple which makes the treatment of complicated flow sheets
