Abstract
The band structure of the doubly odd nucleus Pm-134 has been investigated via the Mo-92(Ti-46, 3pn) Pm-134 and Zn-64(Se-74, 3pn) Pm-134 reactions at beam energies of 210 and 290 MeV, respectively. Two rotational structures showing both signature components have been established. One of these bands has minimal signature splitting and is thought to be built on the pi-[413]5/2 + x vh11/2 configuration. The second band has a small signature splitting and is consistent with a pi-h11/2 x vh11/2 configuration. A third doubly decoupled band has also been observed. Quadrupole moment measurements for this band show that it has a deformation of beta-2 almost-equal-to 0.29. This band is interpreted as being based on pi-h11/2 x vh9/2 configuration. The results are compared with the data from the neighbouring odd-odd N = 73 isotones La-130 and Pr-132 and with cranked shell model and total routhian surface calculations.
