Molecular resonances recently observed in the 12Be⃗6He+6He breakup-reaction experiment are studied by the microscopic coupled-channels (CC) calculation of the 6He+6He scattering, in which excitations of the soft-dipole and quadrupole modes of the colliding 6He nuclei are taken into account in the Goldhaber-Teller model. The CC calculation predicts several molecular-rotational bands in the energy range of the observed resonances and the energies and spins of the calculated resonances agree well with the experimental data.
