The U(5) to SU(3) evolution of the nuclear structure in the even 144-156Nd isotopes has been investigated in the framework of the interacting boson approximation (IBA-2) model, taking into account the effect of the partial Z=64 subshell closure on the structure of the states of a collective nature. The analysis, which led to a satisfactory description of excitation energy patterns, quadrupole moments, and decay properties of the states (even when important M1 components were present in the transitions), is extended to the available data on g factors, in 144-150Nd. Their values are reasonably reproduced by the calculations.

Using new techniques developed for measuring angular correlations with large detector arrays, the g factors of 2+ states in 140,142Xe are measured for the first time by the method of correlation attenuation in randomly oriented magnetic fields. g factors in 146Ba and 146,148Ce are measured to establish the method by comparison with previous values. The results are discussed in terms of IBM-2 and rotation-vibration models.
