Correlation energies for all like ions of two electrons systems (P+13, S+14, Cl+15, Ar+16, K+17and Ca+18) and three electrons systems (P+12, S+13, Cl+14, Ar+15, K+16and Ca+17) are obtained by taking difference between theoretical total energies of H…
Correlation energies for all like ions of two electrons systems (P+13, S+14, Cl+15, Ar+16, K+17and Ca+18) and three electrons systems (P+12, S+13, Cl+14, Ar+15, K+16and Ca+17) are obtained by taking difference between theoretical total energies of Hartree- Fock calculations and experimental total energies.
The atomic properties are calculated very important to describe the dynamics in atomic systems.
In this research used the division technique for the analysis the three electron system, also all the examining atomic properties were normalized and we used the atomic units in our calculations and the results is get by using Mathcad 14 program.
