α-particle production in the scattering of 6He by Pb-208 at energies around the Coulomb barrier
(Elsevier, 2007)
New experimental data from the scattering of 6He + Pb-208 at energies around and below the Coulomb barrier are presented. The yield of breakup products coming from projectile fragmentation is dominated by a strong group ...

O18+Pd110: Measurements and realistic coupled-channel analysis in a transitional region
(American Physical Society, 2006)
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 ...

Observation of two-proton radioactivity of Mg19 by tracking the decay products
(American Physical Society, 2007-10-29)
We have observed the two-proton radioactivity of the previously unknown 19Mg ground state by tracking the decay products in-flight. For the first time, the trajectories of the 2p-decay products, 17Ne+p+p, have been measured ...

Proton-proton correlations observed in two-proton decay of 19Mg and 16Ne
(The American Physical Society, 2008)
Proton-proton correlations were observed for the two-proton decays of the ground states of 19Mg and 16Ne. The trajectories of the respective decay products, 17Ne+p+p and 14O+p+p, were measured by using a tracking technique ...

Experimental determination of the 6,7Li nucleon densities
(American Institute of Physics, 2009)
In this work we present optical model analysis of new near barrier‐quasi‐elastic experimental data, for the systems 6,7Li+120Sn. From the analysis it was possible to extract the ground state nucleon densities of the weakly ...

Experimental determination of the surface density for the 6He exotic nucleus
(American Physical Society, 2003)
Angular distributions for the elastic scattering of 4,6He on 58Ni have been measured at near-barrier energies. The present data, combined with others for the 4He158Ni system at intermediate energies, allowed the determination ...

Near-barrier scattering of 6 He and 11 Be
(American Institute of Physics, 2008)
Experiments on halo nuclei at energies around the Coulomb barrier can provide good quality data on elastic, inelastic, breakup and nucleon transfer reactions. This information turns out to be very important to understand ...

Long range absorption in the scattering of 6 He on 208 Pb and 197 Au at 27 MeV
(Elsevier, 2005)
Quasi-elastic scattering of 6He at E_lab=27 MeV from 197Au has been measured in the angular range of 6-72 degrees in the laboratory system employing LEDA and LAMP detection systems. These data, along with previously analysed ...

γ spectroscopy of 25 , 27 Ne and 26 , 27 Na
(American Physical Society, 2006-12-14)
The γ spectroscopy of 25, 27 Ne and 26, 27 Na was studied from the reaction of 26 Ne with a deuterium target in inverse kinematics at 9.7 MeV/nucleon. The selectivity of the (d,p), (d,t), and (d,n) transfer reactions ...

Scattering of 6He at energies around the Coulomb barrier
(Institute of Physics Publishing, 2005)
We have measured elastic cross sections of the scattering of 6He at ELab = 14, 16, 17, 18, 22 MeV on 208Pb in the angular ranges of 20± − 64± and 135± − 170±. A significant amount of 4He events is found at energies well ...
