The degree of collectivity in the neutron-rich nuclei 32Mg and 34Mg 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 32Mg and 34Mg. The results agree with previous measurements and confirm the placement of both nuclei within the “island of inversion.”
