Investigation of the Na-19 nucleus via resonance elastic scattering Academic Article uri icon


  • The structure of the unbound proton-rich isotope 19Na was studied in resonance elastic scattering of a radioactive 18Ne beam on a proton target using the thick-target inverse-kinematics method. The experiment covered the excitation energy range from 0.5 to 2.7 MeV in c.m.s. Only one state of 19Na (the second excited state) was observed. A combined R-matrix and potential model analysis was performed. The spin and parity assignment of this second excited state was confirmed to be 1/2 +. We show that the position of the 1/2+ state significantly affects the reaction rate through that state, but the total reaction rate remains unchanged since the 18Ne(2p, ) proceeds mostly via the ground and first excited states in 19Na at stellar temperatures.
