Abstract

Calculations of the energy levels of atoms and ions with Z ≤ 10 are carried out in this paper using the complex rotation method. Using a new wave function with two terms including a new method to calculate the correlation factor taking into account spherical harmonics through hypergeometric functions to calculate excited 2sns^+1,3S^e, 2snp^+1,3P⁰, 2pnp^+1,3D^e, 3d4d ^+1,3G^e states. The results obtained show quantitatively the great significance of electron correlation effects in the doubly excited states. These results are in compliance with some experimental and theoretical data.
