    "abstract": "In order to study isovector dipole response of neutron-rich nuclei, we have\napplied a time-dependent method of antisymmetrized molecular dynamics. The\ndipole resonances in Be, B and C isotopes have been investigated. In $^{10}$Be,\n$^{15}$B, $^{16}$C, collective modes of the vibration between a core and\nvalence neutrons cause soft resonances at the excitation energy $E_x=10-15$ MeV\nbelow the giant dipole resonance(GDR). In $^{16}$C, we found that a remarkable\npeak at $E_x=14$ MeV corresponds to coherent motion of four valence neutrons\nagainst a $^{12}$C core, while the GDR arises from the core vibration in the\n$E_x \u003e20$ MeV region. In $^{17}$B and $^{18}$C, the dipole strengths in the low\nenergy region decline compared with those in $^{15}$B and $^{16}$C. We also\ndiscuss the energy weighted sum rule for the $E1$ transitions.",
