Structure of 24Na from 22Ne(3He,p)24Na

In the 22Ne(3He,p)24Na reaction at 18 MeV, excitation energies and angular distributions have been measured for 28 levels below 4.7 MeV in excitation. A distorted-wave analysis identifies the L value for most of these, resulting in Jpi assignments for a number of levels and Jpi restrictions for most levels.

1+ and 0+ states in 90Y

Abstract The 88 Sr( 3 He, p) 90 Y reaction allows the identification of 1 + states at excitation energies of 1816 ± 5 and 2313 ± 10 keV, very close to the predictions of a recent core-coupling shell-model calculation. Three additional 0 + or 1 + states are observed above 3 MeV.

l determinations for 12C + 12C☆

Abstract Detailed angular-distribution measurements and Legendre-polynomial fits for 12 C ( 12 C , α 0 ) 20 Ne ( g.s ) in the bombardi energy region of the so-called “12 + ” bump in 12 C + 12 C inelastic scattering show conclusively that l = 10 dominates the α 0 exit channel throughout the range, except near the narrow 12 + resonance that was previously known.
