Some of the Spanish projects are co-financed by FEDER funds.The beta decay of Pb-192,Pb-190 has been studied using the total absorption technique at the ISOLDE (CERN) facility. The beta-decay strength deduced from the measurements, combined with QRPA theoretical calculations, allow us to infer that the ground states of the Pb-192,Pb-190 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.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttp://dx.doi.org/10.1103/PhysRevC.92.044321http://journals.aps.org/open access539.1Neutron-deficient PBIntruder statesAtomic-nucleiCoexistenceIsotopesSpectraPb-186simulationPoFísica nuclear2207 Física Atómica y Nuclear
