Nuclear spectroscopy of Na24 via (d⃗,p) and (n,γ) reactions

The Na-24 nucleus was investigated via ((d) over right arrow ,p) and (n,gamma) reactions. Within the range of excitation energy from 0 to 6.3 MeV 75 levels were observed. The angular distribution of partial cross sections and vector analyzing powers for 70 levels were determined within the framework of distorted-wave Born approximation. Of 240 gamma transitions assigned to Na-24, 234 were placed in the decay scheme. Based on the extensive (n,gamma) data the neutron separation energy was deduced to be 6959.44+/-0.05 keV. Using spectroscopic information from our ((d) over right arrow ,p) measurement we investigated the role of the direct capture mechanism in the Na-23(n,gamma)Na-24 reaction.
