Abstract
The lifetimes of the low-lying excited states 2<sup>+</sup> and 4<sup>+</sup> have been directly measured in the neutron-deficient <sup>106,108</sup>Sn isotopes. The nuclei were populated via a deep-inelastic reaction and the lifetime measurement was performed employing a differential plunger device. The emitted γ rays were detected by the AGATA array, while the reaction products were uniquely identified by the VAMOS++ magnetic spectrometer. Large-Scale Shell-Model calculations with realistic forces indicate that, independently of the pairing content of the interaction, the quadrupole force is dominant in the B(E2;2<inf>1</inf> <sup>+</sup>→0<inf>g.s.</inf> <sup>+</sup>) values and it describes well the experimental pattern for <sup>104−114</sup>Sn; the B(E2;4<inf>1</inf> <sup>+</sup>→2<inf>1</inf> <sup>+</sup>) values, measured here for the first time, depend critically on a delicate pairing-quadrupole balance, disclosed by the very precise results in <sup>108</sup>Sn.
