Measurement of E2 transition strengths in {sup 32,34}Mg

The degree of collectivity in the neutron-rich nuclei {sup 32}Mg and {sup 34}Mg has been determined via intermediate-energy Coulomb excitation in inverse kinematics. Measured energies of the first excited 2{sup +} states and reduced electric quadrupole transition probabilities B(E2;0{sub g.s.}{sup +}{yields}2{sub 1}{sup +}) are presented for {sup 32}Mg and {sup 34}Mg. The results agree with previous measurements and confirm the placement of both nuclei within the ''island of inversion.''.
