来自 124Xe 碎片的贫中子 106,108,110Sn 稀有同位素束被用于中能库仑激发实验。 108Sn 和 110Sn 的测量 B(E2,0(1)(+)-->2(1)(+)) 值以及 106Sn 获得的结果表明，这些核的转变强度大于当前最先进的壳模型计算的预测值。这种差异可能是由 Z = 50 壳层内的质子对该区域低能激发态结构的贡献来解释的。
Rare isotope beams of neutron-deficient 106,108,110Sn from the fragmentation of 124Xe were employed in an intermediate-energy Coulomb excitation experiment. The measured B(E2,0(1)(+)-->2(1)(+)) values for 108Sn and 110Sn and the results obtained for the 106Sn show that the transition strengths for these nuclei are larger than predicted by current state-of-the-art shell-model calculations. This discrepancy might be explained by contributions of the protons from within the Z = 50 shell to the structure of low-energy excited states in this region.
