17. We note that all channels have K-matrix elements that are nonzero. However, the size of the K-matrix elements decreases very rapidly with the orbital angular momentum of the Rydberg electron. For the level of accuracy desired in a particular problem, there is an effective maximum orbital angular momentum where K-matrix elements for higher angular momentum may be set identically to zero without affecting the calculation.

21. The singlet and triplet partial cross sections are well defined because once the electron leaves the atom there is no interaction that changes the spin coupling since the core is left in an s state.
