“…One of them has a spin parity of J π = 7/2 − and decays to 9/2 + and 5/2 + states of 23 Na by dipole transitions. The assignment is consistent with a l = 3 angular momentum transfer from a (d, n) study [29]. On the otherhand, the measurement also shows a distinct coincidence of a 3914 keV γ ray depopulating the 5/2 + state at 3914 keV excitation with a 5030 keV γ ray that depopulates the relevant 8944 keV state.…”

New measurements of low-energy resonances in theNe22(p,γ)Na23reaction

“…The critical dimensions of the HPGe crystal were measured with a CT scan of the detector [37]. Past studies of the HPGe detector have included extensive geant simulations comparing experimentally measured and simulated γ-ray spectra of radioactive sources including 60 Co, 56 Co, and 137 Cs as well as (p,γ) resonances in 14 N, 18 O, 23 Na, and 27 Al target nuclei [17,34,38]. Comparisons similar to those carried out for the HPGe have been completed for the NaI using 60 Co, the 151-keV resonance in the 18 O(p,γ) 19 F reaction [35], and both resonant and DC spectra from the 17 O(p,γ) 18 F reaction [32].…”

“…[59] and 22 Ne(d,n) 23 Na by Ref. [60], respectively, it should be noted that the 5/2 − assignment in Ref. [23] may actually be based on a misprint in Ref.…”

The Decay of the T = 3/2 Level at 8.66 MeV in 23Na

“…All known levels below 5. 5 MeV excitation energy have been accounted for as members of rotational bands based on Nilsson orbits 3/2+ [211], 1/2+ [211], 1/2+ 12201, 5/2+ [2021 and 1/2-[loll. Above 5.5 MeV the level density increases drastically and due to strong mixing most levels get a very complicated structure.…”
