Nonrelativistic calculation of wavelengths for elements Z = (17–77)

Abstract

In this theoretical study, the nonrelativistic X‑ray wavelengths were calculated for elements with atomic numbers Z = (17–77), where the potential associated with each atom under study was calculated by reducing the nonrelativistic energy with regards to the central potential where the energy values were calculated. The optimal central potential obtained by the variational technique yields an integral equation that can be solved numerically for each atom. Good agreement is observed between the present calculations and the nonrelativistic Hartree–Fock calculations.
