The usual derived relations between the orbital angular momentum and the spin dependence of the unresolved resonance parameters are investigated and the basic underlying assumptions are compared to the most recent experimental data. However, because of the lack of p-wave data, only the assumptions pertaining to s-wave parameters can be verified. Furthermore, it is shown that a previously used level density expression between p() and p(,J) as used by some authors-assuming a (2J + 1) dependence—is in error.
