Atomic integrals containing r 23 λ r 13 μ r 12 ν with λ, μ, ν ≥ −2

In this paper, the efficient evaluation of the atomic integrals I =∫ r   1 ar   2 br   3 cr   23 λr   13 μr   12 νe −α r 1−β r 2−γ r 3 d τ with one or two factors r   ij −2is described. These integrals are necessary for a lower‐bound calculation for Li‐like systems using the method of variance minimization or Temple's formula. © 1993 John Wiley & Sons, Inc.
