The analysis of the Coulomb excitation experiment conducted on Sn-104 required a strict selection of the data in order to reduce the large background present in the gamma-ray energy spectra and identify the gamma-ray peak corresponding to the Coulomb excitation events. As a result the B(E2; 0(+) -> 2(+)) value could be extracted, which established the downward trend towards Sn-100 and therefore the robustness of the N=Z=50 core against quadrupole excitations.
