This a book content number of important subjects related by calculation of atomic properties for ground and excited states of carbon and like ions by using hartree-fock approximation where we study number of wave function such as two -particles density ,two-particles radial density function , one particle radial density function , one particle expectation values ,inter- particles expectation values , standard deviation in addition to calculate all energies of the system as attractive potential energy , repulsion potential energy , total potential energy ,kinetic energy and total energy of the system . All these atomic properties are normalization and the calculation by using atomic units .This properties are very important in industrial applications especially related with semiconductors materials. qassim
