Coulomb excitation of Zn74,76

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 Zn74,76 isotopes. The resulting B(E2; 21+→01+) values are consistent with those determined in earlier REX-ISOLDE measurements...

Descripción
Sumario: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 Zn74,76 isotopes. The resulting B(E2; 21+→01+) values are consistent with those determined in earlier REX-ISOLDE measurements. While the B(E2; 41+→21+) transition probability in Zn76 is also in agreement with earlier Coulomb-excitation results, the value obtained for Zn74 is considerably lower. For the first time, a spectroscopic quadrupole moment of the 21+ 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.
