Study of atomic properties for subshells of the systems have Z=12-16 by using Hartree-Fock approximation

Abstract

Abstract The atomic properties are important to describe of the dynamics in atoms for the two-electron atomic systems studied in this work include the atom Mg, and like ions Al+1, Si+2, P+3 and S+4, Hartree-Fock approximation are used to determine the atomic properties like one electron radial density function D(r1)and its expectation value 〈 r 1 n 〉 , inter electron distribution function f(r 12) and its expectation value 〈 r 12 n 〉 , standard deviation for one and two electrons Δr 1 Δr 12, expectation values for all energies ⟨Ven ⟩, ⟨Vee ⟩, ⟨V⟩, ⟨T⟩, ⟨E⟩
