C 107, 024303 (2023) K.Mizuyama, N.Nhu Le, T.Dieu Thuy, N.Hoang Tung, D.Quang Tam, T.V.Nhan Hao Complex eigenenergy of the giant dipole resonance for 16O by the Jost function within the random-phase approximation framework NUCLEAR STRUCTURE 16O; calculated electric dipole (E1) strength distribution, poles in the complex energy plane corresponding to the RPA excited states (e.g. Giant Dipole Resonance). Jost function method extended within the framework of random phase approximation (Jost-RPA). Comparison to results obtained with continuum RPA (cRPA) calculations. Found that the 16O electric dipole giant resonance is formed by multiple poles, each of which is an independent pole with different widths, origins, response properties to residual interactions, and components structures of the density fluctuation.
