“…Even considering the uncertainties, they are relatively small as compared to the corresponding β C values. This behavior is also observed in the 110 Pd (α, α ) [13] data analysis and others [22] but has not been detected in the nearly spherical 58 Ni region, where β N ≈ β C , as expected.…”

The inelastic, two-neutron and α transfer and quasielastic cross sections for the 18 O+ 110 Pd system have been measured in the near barrier region (40 MeV E lab 58 MeV). The experiments were performed in the São Paulo Pelletron laboratory. Coupled-channel analysis of the experimental data was performed using the São Paulo potential as a microscopic bare interaction. In the calculations, low-lying inelastic excitations, one-and two-neutron and α transfers to the target were considered as the main couplings, with no extra surface absorption. The agreement between the theoretical results and the experimental data is good. The role played by the coupled channels is very different in comparison with similar data analyses for the closed-shell region around 58 Ni.

“…Only in the W isotopes does it seem certain that the observed E0 strength is consistently an order of magnitude smaller than the calculated value. It is known that these nuclei are in a region of hexadecapole deformation [55] and this may offer a qualitative explanation of the suppression of the E0 strength, as argued in the next section.…”

13 pages, 5 tables, 3 figures, accepted for publication in Physical Review CA systematic study of energy spectra throughout the rare-earth region (even-even nuclei from $_{58}$Ce to $_{74}$W) is carried out in the framework of the interacting boson model (IBM), leading to an accurate description of the spherical-to-deformed shape transition in the different isotopic chains. The resulting IBM Hamiltonians are then used for the calculation of nuclear charge radii (including isotope and isomer shifts) and electric monopole transitions with consistent operators for the two observables. The main conclusion of this study is that an IBM description of charge radii and electric monopole transitions is possible for most of the nuclei considered but that it breaks down in the tungsten isotopes. It is suggested that this failure is related to hexadecapole deformation

“…5 The Coulomb-excitation matrix elements and deformation parameters (Table I) used in the analysis, which included only the 0 + and 2 + members of the GSB, were taken from the literature. 6 In order to compare our results to previous low-resolution experiments, the GSB differential cross sections were added, resulting in the familiar Fresnel shape even for the 18 0 + 184 W case. We obtained optical-model parameters (Table I) by fitting this sum in a standard optical-model calculation.…”

Effect of Inelastic Excitation on Elastic Scattering of Heavy Ions

17lh Ref. 15, a model with an enlarged gauge group is constructed in which all such " self-energy" diagrams are finite. The result is, to a good approximation, equivalent to cutting off the divergence in the SU(2) ® U(l) theory with a mass comparable to Af w . 18 Cheng and Li, Ref. 5.The elastic-scattering angular distribution of 90-MeV 18 0 on 184 W exhibits a dramatic deviation from the typical Fresnel shape, which cannot be reproduced by standard optical-model calculations. The effect, a decrease in the elastic cross section below the Rutherford cross section even at forward angles, is due primarily to Coulomb excitation, and will be even more pronounced for heavier projectiles.
