被引用回数:15 パーセンタイル:71.89(Physics, Nuclear)The decay of Pb has been studied using the total absorption technique at the ISOLDE (CERN) facility. The -decay strength deduced from the measurements, combined with QRPA theoretical calculations, allow us to infer that the ground states of the Pb isotopes are spherical. These results represent the first application of the shape determination method using the total absorption technique for heavy nuclei and in a region where there is considerable interest in nuclear shapes and shape effects.

被引用回数:10 パーセンタイル:60.47(Physics, Nuclear)The factor of the first excited state in Zn was measured using the transient-field technique in combination with Coulomb excitation. The experiment was ran at REX-ISOLDE, CERN, and the -ray perturbed angular correlations were measured using 4 triple Germanium clusters of the Miniball array. The experimental result (2) = +0.47(14) is significant to establish the structure of the Zn isotopes near N=40. Comparison with shell-model calculations reveal that to reproduce the measured energies and B(E2) of the Zn isotopes around N=40, both the proton excitations from the orbit and neutron excitations into the and orbits are essential. Furthermore, beyond-mean-field calculations reveal the need to include the triaxial degree of freedom.
