Inverse-kinematics proton scattering by $^{50,52}$Ca

ORAL

Abstract

The deformation lengths of low-lying collective states of $^{52,50}$Ca have been measured via inverse-kinematics proton scattering. A thick liquid hydrogen target was used along with the GRETINA array at the National Superconducting Cyclotron Laboratory. The measured deformation length of the first $2^+$ state of $^{50}$Ca has been combined with the existing lifetime measurement [1] to disentangle the relative proton and neutron contributions to the excitation. Preliminary results will be discussed. \\[4pt] [1] D. Montanari et al., Phys. Rev. C 85, 044301 (2012).
