Abstract

The ��-ray decay of excited states of the one-valence-proton nucleus ������Sb has been studied using cold-neutron induced fission of �������U and �������Pu targets, during the EXILL campaign at the ILL reactor in Grenoble. By using a highly efficient HPGe array, coincidences between ��-rays prompt with the fission event and those delayed up to several tens of microseconds were investigated, allowing to observe, for the first time, high-spin excited states above the 16.6 ��s isomer. Lifetimes analysis, performed by fast-timing techniques with LaBr���(Ce) scintillators, revealed a difference of almost two orders of magnitude in B(M1) strength for transitions between positive-parity medium-spin yrast states. The data are interpreted by a newly developed microscopic model which takes into account couplings between core excitations (both collective and non-collective) of the doubly magic nucleus ������Sn and the valence proton, using the Skyrme effective interaction in a consistent way. The results point to a fast change in the nature of particle-core excitations with increasing spin.

Abstract

5th International Workshop on Nuclear Fission and Fission Product Spectroscopy (FISSION) -- MAY 28-31, 2013 -- Caen, FRANCE, WOS: 000342384500002, Lifetimes of first 4(+) and 6(+) states have been measured in neutron-rich isotopes of Zr, Mo, Ru and Pd using the recoil distance Doppler shift method at GANIL. The nuclei were produced through a fusion-fission reaction in inverse kinematics. The fission fragments were fully identified in the large-acceptance VAMOS spectrometer and gamma -rays were detected in coincidence with the EXOGAM germanium array. Lifetimes of excited states in the range of 1-100 ps were measured with the Cologne plunger. Preliminary lifetime results are presented as well as a discussion on the evolution of the collectivity in this region., ILL, CEA DSM & DAM, CNRS IN2P3, ENSICAEN, GANIL, Scientific and Technological Council of Turkey [210T043], S. Erturk acknowledges the Scientific and Technological Council of Turkey for their support with project number 210T043.
