Direct Measurement of Octupole Deformation in 146Ba
Abstract
The octupole strength present in the neutron-rich, radioactive nucleus 146Ba has been experimentally determined for the first time using Coulomb excitation. To achieve this, A=146 fission fragments from CARIBU were post-accelerated by the Argonne Tandem Linac Accelerator System (ATLAS) and impinged on a thin 208Pb target. Using the GRETINA gamma-ray spectrometer and the CHICO2 heavy-ion counter, the reduced transition probability B(E3; 3- ->0+) was determined as 48(+21/-29) W.u. The new result provides further experimental evidence for the presence of a region of octupole deformation surrounding the neutron-rich barium isotopes.
