Calculation of the energies of k-shell for atoms (Z=8 to 10)‎ by sing Hartree-Fock method

الملخص EN

The atomic properties are important to describe of the dynamics in atoms for the two-electron atomic systems studied in this work include the neutral atom O, F and Ne ,Hartree-Fock wave functions are used to determine the atomic properties like one electron radial density function Dfri)and its expectation value (r "} ,inter electron distribution function f(r12) and its expectation value {712), two electron radial density function D( rhr2 ), standard deviation for one and two electrons Ar± Ar12 expectation values for all energies (O
