Abstract.
The measured spectroscopic quadrupole moments and deduced deformations of the 194,196Pb(11-) intruder isomers are reevaluated, making use of the recently measured magnetic moments of these states. This adjustment is necessary since the quadrupole moments were obtained from Level Mixing Spectroscopy measurements, being sensitive to the ratio of the quadrupole interaction frequency and the magnetic moment. The results confirm the moderate deformation of the \(\ensuremath{\pi(3s_{1/2}^{-2}1h_{9/2}1i_{13/2})_{11^{-}}}\) states. A systematic comparison between the updated experimental and the available theoretical values is presented.
