We propose here an extended framework for antisymmetrized molecular dynamics (AMD) to describe the halo structure involving core excitation. We have applied this model to He isotopes, ^8B, and ^9C. Binding energies and radii in He isotopes are reproduced well by the present model, and the wave functions describe the spatial extension of the density distribution. These results indicate that a reasonable description of the halo structure is achieved in this model. Furthermore, the halo structure involving core excitation is found in ^8B and ^9C. The cluster structure in the core plays an important role in explaining the observed electric quadrupole and magnetic dipole moments in these nuclei.
