Nuclear moments of micro-second isomeric fragments at BigRIPS

The measurement of nuclear moments of a μ-second isomeric state have been successfully performed using the RIKEN Radioactive Ion Beam Facility. The Time Dependent Perturbed Angular Distribution technique was applied on the 43S isomeric state produced by the fragmentation of a 48Ca beam and selected with the BigRIPS spectrometer. Following the measurement of the known g-factor of the isomer the quadrupole moment of this state was measured. Its spectroscopic quadrupole moment |QS| = 23(3) efm2 agreed with both shell model and beyond mean field calculations. ispartof: pages:33-40 ispartof: Proceedings of the French–Japanese Symposium pages:33-40 ispartof: LIA 2011 symposium location:RIKEN, Wako, Japan date:5 Jan - 8 Jan 2011 status: published
