Abstract

The degree of collectivity in the neutron-rich nuclei ${}^{32}{Mg}$ and ${}^{34}{Mg}$ 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 $B (E 2; 0_{g.s.}^{+} \to 2_{1}^{+})$ are presented for ${}^{32}{Mg}$ and ${}^{34}{Mg}$ . The results agree with previous measurements and confirm the placement of both nuclei within the “island of inversion.”
