Coulomb excitation of ^74,76Zn

Summary, in English

The first experiment using radioactive beams post-accelerated by the HIE-ISOLDE facility has enabled to obtain a precise set of B(E2) transition probabilities in neutron-rich ^74,76Zn isotopes. The resulting B(E2; 2⁺₁→0⁺₁) values are consistent with those determined in earlier REX-ISOLDE measurements. While the B(E2; 4⁺₁→2⁺₁) transition probability in ⁷⁶Zn is also in agreement with earlier Coulomb-excitation results, the value obtained for ⁷⁴Zn is considerably lower. For the first time, a spectroscopic quadrupole moment of the 2⁺₁ state was measured for an exotic nucleus in this mass region. A detailed comparison is presented with large-scale shell-model and Monte Carlo shell-model calculations.
