AbstractIt is studied how the alpha cluster degrees of freedom, such as alpha clustering configurations close to the alpha decay threshold in C-12 and O-16, including the linear chain, triangle, square, kite, and tetrahedron, affect nuclear collective vibrations with a microscopic dynamical approach, which can describe properties of nuclear ground states well across the nuclide chart and reproduce the standard giant dipole resonance (GDR) of O-16 quite nicely. It is found that the GDR spectrum is highly fragmented into several apparent peaks due to the alpha structure. The different alpha cluster configurations in C-12 and O-16 have corresponding characteristic spectra of GDR. The number and centroid energies of peaks in the GDR spectra can be reasonably explained by the geometrical and dynamical symmetries of alpha clustering configurations. Therefore, the GDR can be regarded as a very effective probe to diagnose the different alpha cluster configurations in light nuclei.
