Analysis and results of the 104 Sn Coulomb excitation experiment

The analysis of the Coulomb excitation experiment conducted on 104 Sn required a strict selection of the data in order to reduce the large background present in the γ-ray energy spectra and identify the γ-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 100 Sn and therefore the robustness of the N=Z=50 core against quadrupole excitations.
