Abstract: | The level structure of123Xe has been studied with the114Cd (12C, 3n) and?Cd (13C, 4n) reactions using in-beamγ-ray spectroscopy. The yrast cascade on the low lying odd parity states originating from theh 11/2 neutron orbital has been investigated yielding lifetimesτ of 18(3) ps, 2.2 (4) ns and 17(2) ns for the 15/2?, 11/2? and 9/2? states, respectively. Theg-factor of thet 1/2=5.2 μs isomer has been measured to beg=?0.256(2). From the time differential observation of the electric quadrupole interaction in a114Cd single crystal the spin of this isomer has been determined to be 7/2 and from the coupling constante 2 Qq/h=116(2) MHz the quadrupole moment was deduced. The results are discussed in the framework of the triaxial rotor plus particle model. |
