The degree of collectivity in the neutron-rich nuclei Mg32 and Mg34 has been determined via intermediate-energy Coulomb excitation in inverse kinematics. Measured energies of the first excited 2+ states and reduced electric quadrupole transition probabilities B(E2;0g.s.+→21+) are presented for Mg32 and Mg34. The results agree with previous measurements and confirm the placement of both nuclei within the "island of inversion.
