AbstractThe a cluster states are discussed in a model frame of extended quantum molecular dynamics. Different a cluster structures are studied in detail, such as Be-8 two-a cluster structure, C-12 triangle structure, C-12 chain structure, O-16 chain structure, O-16 kite structure, and O-16 square structure. The properties studied include the width of wave packets for different a clusters, momentum distribution, and the binding energy among a clusters. We also discuss how the a cluster degree of freedom affects nuclear collective vibrations. The cluster configurations in C-12 and O-16 are found to have corresponding characteristic spectra of giant dipole resonance (GDR), and the coherences of different a clusters' dipole oscillations are described in detail. The geometrical and dynamical symmetries of alpha-clustering configurations are responsible for the number and centroid energies of peaks of GDR spectra. Therefore, the GDR can be regarded as an effective probe to diagnose different a cluster configurations in light nuclei.
