Inverse kinematics proton scattering on 18Ne and mirror symmetry in A=18 nuclei

The 0(g.s.)(+) --> 2(1)(+) transition in Ne-18 has been studied using the inverse kinematics reaction p(Ne-18, p') with a radioactive Ne-18 beam at 30 MeV/nucleon. Hadronic scattering data on the 0(g.s.)(+) -->2(1)(+) transition in the mirror nucleus O-18 are already available, so this is the first time that hadronic measurements have been available to test mirror symmetry in s-d shell nuclei. The angular distribution data for proton inelastic scattering in 18Ne and corresponding data for O-18 are well reproduced in microscopic model calculations using empirical proton and neutron transition densities determined for O-18.
