We have analyzed large-amplitude quadrupole collective dynamics in neutron-rich nuclei 30−36Mg using the five-dimensional quadrupole collective Hamiltonian approach. The collective Hamiltonian is microscopically derived with the constrained HFB plus local quasiparticle RPA method. Enhancement of the quadrupole collectivity from Mg to Mg is well described by the calculation. The shape transitional behavior in the ground band and the shape coexistence/mixing properties in the ground and excited 0 states are analyzed.
