Molecular states in highly-excited Be-12 and Be-10

Molecular resonances having the He-6+He-6 and He-4+He-6 structures, which h ave recently been observed in the highly excited Be-12 and Be-10, respectiv ely, are studied by the microscopic coupled-channels (CC) calculation in wh ich excitations of the soft-dipole and quadrupole modes of the colliding He -6 nuclei are taken into account in the Goldhaber-Teller model. The CC calc ulation predicts several molecular-rotational bands in the energy range of the observed resonances and the energies and spins of the calculated resona nces agree well with the experimental data.
