Abstract: (APS)

Low-lying excited states of Ar46 have been studied via inverse-kinematics proton scattering with a thick target. Coupled-channels calculations have been used to extract the deformation length of the 21+ state. This result, combined with existing Coulomb excitation data, yields a ratio of the neutron-to-proton transition matrix elements of Mn/Mp=1.19(25)N/Z, showing a departure from the proton dominance observed in the N=28 isotones above Ca48. The status of the N=28 shell below Ca48 is discussed.
