The role of quadrupole and octupole collectivity in the shape-transitional nucleus 148 Nd has been studied by Coulomb excitation using beams of 58 Ni and 92 Mo, and a beam of 148 Nd (using a 208 Pb target). The extracted E1, E2 and E3 matrix elements

Pb-195 was investigated utilizing the reactions Dy-164(S-36, 5n)Pb-195 and Dy-164(S-34, 3n)Pb-195 at beam energies of 170 and 160MeV respectively. Two new dipole bands which feed into the yrast 25/2(+) state, were found in Pb-195. The connection betw

We have applied gamma-ray spectroscopy and selection techniques to study for the first time high spin states in [sup 114]Xe. This provides evidence for broken reflection symmetry near the [ital N]=[ital Z] line in medium-mass nuclei. We discuss simpl

The quadrupole moments of the upsilon i13/2 intruder bands in 135,135Sm have been deduced from nuclear lifetimes measured using the Doppler shift attenuation method. A centroid shift analysis of the data yielded values of Q0=7.0 eb and 5.0 eb for 135
