Subject: Pekeris Technique for 2-electron Atoms

I'm currently working on 2-electron atoms using Pekeris' approach (see
Phys Rev 112, 1649 (1958) and Phys Rev 115, 1216 (1959)). I believe that
Equation 22 of the 1958 paper has an error in it, because the results
don't agree with the special case results for the 7x7 case that Pekeris
puts on the following page of that paper. I've checked my work several
times, but there still appears to be something wrong. 

I looked for, but did not find, a published errata for this paper, which
concerns me, since they've certainly had time to get a correction out,
so I could be doing something dumb.

Has anyone else worked through this paper? If so, could they offer me
any help. Thanks very much in advance.
