Careful comparison of F and Na, and available data on reactions leading to both, suggests that J (2646) =3+. Other mirror identifications are indicated and quantities of astrophysical interest are calculated. PACS number(s): 27.30.+t, 97.10.CvThe region of excitation energy just above 2.2 MeV in Na is important because of the possibility of a resonance in the astrophysically interesting [1 -3] reaction ' Ne(p, y) Na. Above the ' Ne+p threshold at 2199 keV, the first known state [4 -7] is at 2646 keV (see Fig. 1). This state, which is presumed to be the strongest (p, y) resonance, is strongly populated [4 -6] in Ne( He, t) Na and has been variously and incorrectly identified [4 -6] as the mirror of the 3173or 3488-keV
