Abstract

The ²⁴Mg(p, α)²¹Na reaction was measured at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory in order to better constrain the spins and parities of the energy levels in ²¹Na for the astrophysically important ¹⁷F(α, p)²⁰Ne reaction rate calculation. 31-MeV proton beams from the 25-MV tandem accelerator and enriched ²⁴Mg solid targets were used. Recoiling ⁴He particles from the ²⁴Mg(p, α)²¹Na reaction were detected by a highly segmented silicon detector array which measured the yields of ⁴He particles over a range of angles simultaneously. A new level at 6661 ± 5 keV was observed in the present work. The extracted angular distributions for the first four levels of ²¹Na and the results from distorted wave Born approximation (DWBA) calculations were compared to verify and extract the angular momentum transfer.
