The 0g.s.+→21+ transition in 18Ne has been studied using the inverse kinematics reaction p(18Ne,p′) with a radioactive 18Ne beam at 30 MeV/nucleon. Hadronic scattering data on the 0g.s.+→21+ transition in the mirror nucleus 18O 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 18O are well reproduced in microscopic model calculations using empirical proton and neutron transition densities determined for 18O.
