Fast timing results from EXILL&FATIMA for fission fragments in the neutron-rich region around Z=40, N=60. — •Jan Jolie1, Jean-Marc Régis1, Saba Ansari1,2, Nima Saed-Samii1, and Nigel Warr1 — 1Institut für Kernphysik, Universität zu Köln, Zülpicher Str. 77, 50937 Köln — 2CEA de Saclay, IRFU, 91191 Gif-sur-Yvette, France
Several lifetimes or lifetime limits were measured in the even-even Strontium isotopes 94-Sr, 96-Sr and 98-Sr [1] and Zirconium isotopes 98-Zr, 100-Zr, and 102-Zr [2] using the EXILL&FATIMA array [3] to perform fast electronic timing on fission products produced after cold neutron capture in 235U. Absolute values and limits for the lifetimes of the lowest yrast states could be determined. The results are compared to state-of-the-art Monte Carlo Shell Model calculations and to several predictions based on Energy Density Functionals. Supported by the BMBF, Grant No. 05P15PKFNA.
