Time-dependent density-functional studies on strength functions in
neutron-rich nuclei    [PDF]

Shuichiro Ebata, Tsunenori Inakura, Takashi Nakatsukasa

The electric dipole (E1) strength functions have been systematically calculated based on the time-dependent density functional theory (TDDFT), using the finite amplitude method and the real-time approach to the TDDFT with pairing correlations. The low-energy E1 strengths in neutron-rich isotopes show peculiar behaviors, such as sudden enhancement and reduction, as functions of the neutron numbers.They seem to be due to the interplay between the neutron shell effect and the deformation effect.
