Abstract

Radial expectation values, < r >, for helium like actinides (Z(Ac)=89, Z(Th)=90, Z(Pa)=91, Z(U)=92, and Z(Np)=93) are reported using the Multiconfiguration Hartree-Fock (MCHF) within the framework Breit-Pauli corrections. Atomic data as energy levels, wavelengths, weighted oscillator strengths, and transition probabilities for allowed and forbidden transitions need these calculations. The obtained results are compared available works.
