Abstract
We present an implementaion of the Feshbach formalism to calculate energy positions and widths of doubly excited states of Be-like ions. These systems can be treated formally as two-electron problems by using a suitable model potential to describe the effect of the 1 core. In this respect, we discuss the pertinence of using the one-parameter model potential =2-2(1+αr). Energies and widths for 14l4l’ and autoionizing states of and are reported.
