The reduced transition probability B(E2)\ensuremath\uparrow of the first excited 2+ state in the nucleus 104Sn was measured via Coulomb excitation in inverse kinematics at intermediate energies. A value of 0.173(28) e2b2 was extracted from the absolute cross section on a Pb target. Feeding contributions in 104Sn from higher lying states were estimated by a reference measurement of the stable 112Sn. Corresponding only to a moderate decrease of excitation strength relative to the almost constant values observed in the proton-rich, even-A ^106\ensuremath-114Sn isotopes, present state-of-the-art shell-model predictions, which include proton and neutron excitations across the N=Z=50 shell closures as well as standard polarization charges, underestimate the experimental findings.
