Abstract
A self-consistent approach to describing isobaric analog resonances (IAR) in neutron-rich nuclei that involve pairing is developed. The continuum quasiparticle random-phase approximation based on a new modification of the energy density functional proposed by Fayans and his coauthors is used for this purpose. The properties of IAR in heavy calcium, tin, and lead isotopes, including those that are close to doubly magic ones and those that involve developed neutron pairing, are calculated. The results are compared with their counterparts calculated on the basis self-consistent models implemented by employing various relativistic functionals and Skyrme functionals.
