Study of single-particle resonant states

Energies and widths for single-particle resonant states in the continuum in Sn-120, as the necessary input quantities of relativistic random phase approximation for the investigation of isoscalar giant octupole resonance, are determined by analytic continuation in the coupling constant (ACCC) method within the framework of self-consistent relativistic mean field (RMF) theory for the first time. For the effective interaction NL3, the results in this scheme agree well with those of scattering phase shift method on the basis of RMF. Similar calculations are carried out in neutron-rich nucleus Ni-84.Physics, NuclearPhysics, Particles & FieldsPhysics, MathematicalSCI(E)4ARTICLE201537-15451
