S. Schmidt et al., NA-22(HE-3,D)MG-23 REACTION STUDIES OF STATES NEAR THE PROTON THRESHOLD AND HYDROGEN BURNING OF NA-22, Nuclear physics. A, 591(2), 1995, pp. 227-243
The Na-22(He-3,d)Mg-23 reaction has been investigated at E(tau)= 30 Me
V using a Na-22 implanted foil target and a Q3D spectrograph of high e
nergy resolution. The angular distributions of deuteron groups corresp
onding to nineteen Mg-23 levels between E(x) = 6236 and 8076 keV have
been measured at angles theta(lab) = 7.5 degrees to 31 degrees and lea
d to their proton spectroscopic factors using DWBA analysis. The Na-22
(p,gamma)Mg-23 resonance strengths for unbound states near the proton
threshold have been deduced. The resulting reaction rates significantl
y reduce previous uncertainties.
