Abstract
The static moments and isomer shift of the Jπ = Kπ = 8- isomeric state in 56130Ba have been measured using the technique of collinear laser spectroscopy. The isomer has been found to have a magnetic dipole moment of -0.043(28) μN and a static quadrupole moment of +2.77(30) b. These values have been used to assign the state as a two neutron 7/2+[404] ⊗ 9/2-[514] configuration corresponding to a prolate shape. The half-life of the isomer has been confirmed as 9.54(14) ms. The change in the mean square charge radius was found to be (r2)130m - (r2)130g-s = -0.0473(30) fm2. © 2002 Published by Elsevier Science B.V.
