摘要：

A fully consistent relativistic continuum random phase approximation (RCRPA) is constructed in termsof the Green’s function technique. In this method the contribution of the continuum spectrum to nuclear excitations istreated exactly by the single particle Green’s function, which includes also the negative states in the Dirac sea in theno sea approximation. The theoretical formalism of RCRPA and numerical details are presented. The single particleGreen’s function is calculated numerically by a proper product of regular and irregular solutions of the Dirac equation.The numerical details and the formalism of RCRPA in the momentum representation are presented.
