Abstract：
¹⁹Na, a nuclide on proton drip line, was studied by ²⁰Ne(p,2n) ¹⁹Na reaction.Experiment was performed on the proton linear accelerator at institute of High Energy Physics, The Chinese Academy of Sciences. The new decay mode of β-delayed proton decay was observed for the first time. The half-life of ¹⁹Na was determined to be 47±20ms and its proton energy was measured to be 1.10±0.08MeV which is corresponding to super-allowed beta transition of ¹⁹Na to excited state of 7.62MeV,the isospin analog state with T=3/2 in ¹⁹Ne, and subsquent proton emission to the ground state of ¹⁸F.
