I wish to thank Dr. M. Miskowski for pointing out the importance of the pairing energy correction and Professor A. B. P. Lever for pointing out the uncertainty in the AOM parameters arising from the energy contribution W.-Jeffrey I. Zink

Pages 1015 and 1016. The contribution of the pairing energy to the spectroscopic parameters was not calculated. The equations which are changed when the pairing energy is included are

In addition, they include an uncertainty of i 1 . 0 from the uncertainty in D. Ds and Dt are not changed. Note that the consistency between the LF and AOM parameters is required by the calculation and is not a test of validity.
