Calculation of the correlation energy of three electron systems of 20 to 25 electrons

Year: 2023

Type: article

Abstract: In this research the Hartree- Fock energies were calculated for three-electron systems (Ca+17 , Sc+18, Ti+19, V+20 , Cr+21 and Mn+22) have (Z=20-25) are obtained by an account the atomic properties by using the Hartree- Fock method and Mathcad 14 program, the total expectation value energy 〈EHF〉 and the correlation energy are important property account in this research and when comparing the result with published results. It was found that there is a good agreement.
