The 0g.s.+→21+ excitation in the proton-rich nucleus 18Ne has been studied via intermediate energy heavy-ion scattering with a beam of this radioactive isotope. The observed γ-ray yields have been combined with coupled channels calculations of the inelastic scattering reactions to obtain the electromagnetic matrix element B(E2;0g.s.+→21+). This result is combined with the corresponding results in the mirror nucleus 18O and the T=1 states in the N=Z nucleus 18F as a test of isospin purity.
