dc.descriptionArtículo firmado por 37 autores. We are grateful to F. Iachello, R. F. Casten, and D. Bonatsos for useful discussions. The EXILL&FATIMA campaign would not have been possible without the support of several services at the ILL and the LPSC. We are grateful to the EXOGAM collaboration for the loan of the detectors, to GANIL for assistance during installation and dismantling, and to the FATIMA collaboration for the provision of LaBr3 (Ce) detectors and analog electronics. This work was supported by the cooperation between TU Darmstadt and the GSI Helmholtz Center for Heavy Ion Research and by the Helmholtz Graduate School for Hadron and Ion Research for FAIR, by the QuantiXLie Centre of Excellence, a project co-financed by the Croatian Government and European Union through the European Regional Development Fund - the Competitiveness and Cohesion Operational Programme (Grant No. KK.01.1.1.01), by US DOE under Grant No. DE-FG02-91ER-40609, by UK Science and Technologies Facilities Council (STFC) under Grants No. ST/L005743/1, No. ST/G000751/1, No. ST\L\0057\1, and No. ST\P005314\1, by Istanbul University Scientific Research Project No. 54135, by DFG under Grants No. KR 1796/2-1,2 and No. SFB1245 and by BMBF under Grants No. 05P12RDNUP, No. 05P(15/19)RDFN1, No. 05P(15/19)PKFNA, and No. 05P12PKNUF.

dc.description.abstractExcited states of the neutron-rich nucleus Ce-148 have been populated by neutron-induced fission of a U-235 target. Its electromagnetic decays were studied by means of gamma-ray coincidence spectroscopy with fast-timing capabilities. Lifetimes of the 2(1)(+) and 4(1)(+) states of Ce-148 were obtained and their E2 decay rates deduced. The B-4/2 = B(E2; 4(1)(+) -> 2(1)(+))/B(E2; 2(1)(+) -> 0(1)(+)) ratio indicates that Ce-148 is a transitional nucleus while the N = 88/90 shape phase transition evolves into a gradual change of nuclear deformation for proton numbers Z < 60.
