The inelastic, two-neutron and α transfer and quasielastic cross sections for the 18O+110Pd system have been measured in the near barrier region (40 MeV Elab 58 MeV). The experiments were performed in the S˜ao Paulo Pelletron laboratory. Coupled-channel analysis of the experimental data was performed using the S˜ao 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 58Ni.

We present results on radiocarbon dating of foraminifera shell samples, collected on the upper slope of Campos Basin, in Southern Brazil. This is the first time that the sedimentation rate of this area is measured with a fine scale (cm) stratigraphy. C-14 ages vary from (2560 +/- 80) years. BP at the top to (7260 +/- 80) years. BP at the bottom of the sediment column. The mean accumulation ratio for the whole column is (6.2 +/- 0.7) cm/kyears. (C) 2004 Elsevier B.V. All rights reserved.

Complete fusion excitation functions for $^{9}$Be + $^{208}$Pb have been measured to high precision at near barrier energies. The experimental fusion barrier distribution extracted from these data allows reliable prediction of the expected complete fusion cross-sections. However, the measured cross-sections are only 68% of those predicted. The large cross-sections observed for incomplete fusion products support the interpretation that this suppression of fusion is caused by $^{9}$Be breaking up into charged fragments before reaching the fusion barrier. Implications for the fusion of radioactive nuclei are discussed., Comment: RevTex, 11 pages, 2 postscript figures, to appear in PRL
