Abstract

²²Na is an important isotope for the study of extinct radioactivity, meanwhile its sufficiently long half life provides the possibility to observe live ²²Na in nearby nova explosions. The ²²Na(p,γ) ²³Mg is one of the key reactions that influence the ²²Na abundance in nova ejecta. To study the proton resonant states in ²³Mg relevant to the astrophysical ²²Na(p,γ) ²³Mg reaction rates, two measurements have been carried out at the CRIB separator of University of Tokyo, and the RIBLL secondary beamline in Lanzhou, respectively. The ²²Na secondary beam was produced via the ¹H(²²Ne, ²²Na)n charge exchange reaction. Thick-target inverse-kinematics method is applied to obtain the excitation function of ²²Na+p elastic scattering. Extended gas target and solid state polyethylene foil were used in the two measurements, respectively, to map the different excitation energy region of the compound nucleus ²³Mg. Several new resonant levels are observed and their contribution to the ²²Na(p,γ) ²³Mg reaction rate is evaluated.
