Ba. Brown et al., NATURE OF THE NA-20 2646-KEV LEVEL AND THE STELLAR REACTION-RATE FOR NE-19(P,GAMMA)NA-20, Physical review. C. Nuclear physics, 48(3), 1993, pp. 1456-1459
Careful comparison of F-20 and Na-20, and available data on reactions
leading to both, suggests that J(pi)(2646)=3+. Other mirror identifica
tions are indicated and quantities of astrophysical interest are calcu
lated.
