dc.description© American Physical Society 2017. Artículo firmado por más de 10 autores We would like to thank J. M. Yao and K. Nomura for making available results of their calculations not shown in Refs. [24,25]. This work was supported by NuPNET and the German BMBF by Contracts 05P12PKNUF and 05P12DRNUP, the Spanish MINECO via Projects FPA2010-17142, CPAN (CSD 2007-00042) and PRI-PIMNUP-2011-1338 within the ERA-NET NuPNET call for translational joint activities, the UK STFC Contract No. DNC7RP01/4 and the UK National Measurement Office. 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 LaBr<INF>3</INF>(Ce) detectors and analog electronics. Theoretical studies including MCSM calculations were supported in part by JSPS Grants-in-Aid for Scientific Research (23244049), in part by HPCI Strategic Program (hp150224), in part by MEXT and JICFuS and Priority Issue on Post-K computer (Elucidation of the fundamental laws and evolution of the universe) (hp160211), and by the CNS-RIKEN joint project for large-scale nuclear structure calculations.
dc.description.abstractLifetimes of low-lying yrast states in neutron-rich Sr-94,Sr-96,Sr-98 have been measured by Germanium-gated gamma-gamma fast timing with LaBr3(Ce) detectors using the EXILL& FATIMA spectrometer at the Institut Laue-Langevin. Sr fission products were generated using cold-neutron-induced fission of 235U and stopped almost instantaneously within the thick target. The experimental B(E2) values are compared with results of Monte Carlo shell-model calculations made without truncation on the occupation numbers of the orbits spanned by eight proton and eight neutron orbits and show good agreement. Similarly to the Zr isotopes, the abrupt shape transition in the Sr isotopes near neutron number N = 60 is identified as being caused by many-proton excitations to its g(9/2) orbit.
