THE REACTION $sup 20$Ne(p,$gamma$$)$$sup 21$Na
The decay scheme, the width, and the strength of the E/sub p/ = /sup 20/ Ne(p, gamma )/sup 21/Na are reported. The spins of the first two resonances are J/sup pi / = 5/2/sup +/ and 5/2, respectively. Coincidence and angular correlation measurements at the E/sub p/ = 1955 kev resonance yield the excitation energy and spin of the /sup 21/Na first excited state: E/sub x/= 338 plus or minus 3 kev and J/sup pi / = 5/2/sup +/. The mi xing ratio of the 0.34- Mev gamma ray de-exciting this level is x = 0.05 plus or minus 0.05. Measurements of the resonance- and gamma -ray energies yield the reaction Q value, Q = 2424 plus or minus 10 kev. The corresponding /sup 21/Na mass excess is -2177 plus or minus 10 kev. (auth)
