• Abstract

  The objective of the present proposal is to enhance the ongoing collaboration between IFUSP and the LNS/INFN by facilitating the exchange of researchers and expertise. Both institutions have ongoing research projects which share some technical characteristics, and address important nuclear reaction mechanism topics. The NUMEN project (lNFN) is a large international collaboration to measur…

• Abstract

  The assemblage of new types of detectors for the measurement with weakly bound stable and radioactive beams is proposed. The experimental setups with these detectors, involving kinematic coincidence between charged particles and gamma rays, will allow the detailed investigation of the break-up mechanisms of weakly bound nuclei, which have a well known importance in atrophysical processes,…

• Abstract

  A model for light pulse transmission in phoswich plastic scintillator detectors is proposed for the extraction of the incidence position of charged particles in two dimensions. Computer programs will be developed for implementation of the theoretical model, and for parameter adjustments based on the comparison with existing experimental data with alpha particles. It is expected that the m…

  A FAPESP Regular Project n. 2016/04612-9 is under devellopment at the DFN-IFUSP, coordinated by the supervisor, involving the construction and use of a gamma spectrometer for experiments to measure nuclear reaction mechanisms by the particle-gamma coincidence techique. In this project new generation inorganic scintillators, such as GAGG(Ce) and LYSO(Ce) crystals will be used as gamma dete…

• Abstract

  We purpose to measure the 7Li + 120,122Sn reactions in of 18 to 26 MeV by the gamma-charged particle coincidence technique with Saci-Perere spectrometer. These kind of measurements are unpublished and allow to obtain simultaneously the cross sections of inelastic channels and the transfer to excited and incomplete fusion channels, as a function of the scattering angle and beam energy, bes…

• Abstract

  The measurement of the nuclear reaction of 16O+60Ni at 280 MeV will be performed with the MAGNEX spectrometer. The beam will be provided by the Superconducting Cyclotron (CS) of the Laboratori Nazionali del Sud (LNS), Catania, Italy. The objective is to verify the predictions, based on coupled channel calculations with a Sao Paulo potential optical model, of the ocurrence of rainbow-like …

• Abstract

  The elastic scattering of 16O+27Al at 280 MeV should be measured with the MAGNEX spectrometer at LNS/INFN (Catania, Italy) in order to verify and characterize the role of couplings in the formation of a nuclear rainbow pattern according to predictions based in our model for the reaction mechanism.
