Abstract

The unstable neutron-deficient Sn108 isotope has been studied in inverse kinematics by intermediate-energy Coulomb excitation using the RISING/FRS experimental setup at GSI. This is the highest Z nucleus studied so far with this method. Its reduced transition probability B (E2;0g.s.+â†21+) has been measured for the first time. The extracted B(E2) value of 0.230(57)e2b2 has been determined relative to the known value in the stable Sn112 isotope. The result is discussed in the framework of recent large-scale shell model calculations performed with realistic effective interactions. The roles of particle-hole excitations of the Sn100 core and of the Z=50 shell gap for the E2 polarization are investigated.
