Nuclear excitation energies and reaction Q-values were measured with the M.S.U. cyclotron--magnetic spectrograph system with uncertainties on the order of 1 keV or less. The method involves a spectrograph calibration procedure which utilizes a combination of momentum-matching and kinematics techniques. The calibration lines used in the present work are independent of any previous spectrograph based on the /sup 210/Po( alpha ) energy scale. The present work is also largely independent of Ge(Li) gamma detector measurements, and provides independent consistency checks on previous measurements at the 1-keV uncertainty level. Sample results include checks on the excitation energies of the first excited state of /sup 12/C and the third excited state of /sup 24/Mg. The excitation energy of the flrst excited state of /sup 11/C and the Q-values for the reactions /sup 24/Mg(p,d)/sup 23/Mg and /sup 24/Mg(p,t)/sup 22/Mg are al so presented.
