GAMMA RADIATIONS OF Na$sup 23$ AND Ne$sup 20$ (thesis)

Technical Report ·
OSTI ID:4250066
Na/sup 23/ and Ne/sup 20/ gamma rays were observed from the proton bombardnnent at various energies of thin evaporated Na and Nal targets and of a natural Ne target. Gamma rays involving Na/sup 23/ states up to 4 Mev and Ne/sup 20/ states up to 5 Mev were observed and decay schemes and branching ratios obtained. Spin and parity assignments, or limitations of the possible values, are made for these states. The 2.08 and 2.70 Mev states of Na/sup 20/ are probably 7/2/sup +/ and 9/2//sup +/ respectively. The results obtained for Na/ sup 23/ are consistent with a strong-coupling collective calculation. The 4.97 Mev state of Ne/sup 20/ has an upper limit for the ground state branch of about 4%. An upper limit of 10% is placed on the ground state branch of the 4,2 Mev state of Ne/sup 20/. (auth)
