Evaluation And Comparison Of The Configuration Potential Energy Calculation For Be-Atom In Position Space
In the present work studies the theoretically the potential energy expectation value 〈V〉 for beryllium atom and like ions for different excited states ( , ( ) (where Z = 4. 13) and calculate the difference between each state to the same level , was used in this study wave function Hartree – Fook and the results contained in this search match with the published results of Hartree – Fook in 2003 (source 25) . been taking values of (n = 4, 5) to the( state and (n = 2, 3) of the ( ) state . The computer system Mathcad (Ver 2001i) is used in the present calculations after designing the required program.
