• We propose a new method of the β-γ constraint for quadrupole deformation in antisymmetrized molecular dynamics (AMD) to describe various cluster and shell-model structures in the ground and excited states of light nuclei. We apply this method to N=6 isotones, ^<10>Be, ^<12>C, ^9Li, and ^<11>B, and find various structures as functions of the deformation parametersrs, β and γ. In these nuclei, shell-model-like structures appear in the small β region, while cluster structures develop well in the large β region where various geometric configurations of clusters are obtained depending on the γ parameter. For ^<10>Be and ^<12>C, we superpose the basis AMD wave functions obtained by the β-γ constraint method to calculate energy spectra, and prove the advantages of the present method of the two-dimenensional β-γ constraint in the framework of AMD.
