Coulomb excitation of 107Sn

The radioactive isotope 107Sn was studied using Coulomb excitation at the REX-ISOLDE facility at CERN. This is the lightest odd-Sn nucleus examined using this technique. The reduced transition probability of the lowest-lying
\ensuremath
3
/
2
+
state was measured and is compared to shell-model predictions based on several sets of single-neutron energies relative to 100Sn . Similar to the transition probabilities for the
\ensuremath
2
+
states in the neutron-deficient even-even Sn nuclei, the measured value is underestimated by shell-model calculations. Part of the strength may be recovered by considering the ordering of the
\ensuremath
𝑑
5
/
2
and
\ensuremath
𝑔
7
/
2
single-neutron states.
