Artigo IPEN-doc 20876 Measurement of fusion cross sections for sup(16)O+sup(16)(O)2015 - DUARTE, J.G.; GASQUES, L.R.; OLIVEIRA, J.R.B.; ZAGATTO, V.A.B.; CHAMON, L.C.; MEDINA, N.H.; ADDED, N.; SEALE, W.A.; ALCANTARA NUNEZ, J.A.; ROSSI JUNIOR, E.S.; AMADOR VALENZUELA, P.; LEPINE SZILY, A.; FREITAS, A.S.; SCARDUELLI, V.; AGUIAR, V.A.P.; SHORTO, J.M.B.In earlier works, the fusion cross section for the 16O+16O reaction has been measured using different techniques. In the present work, we have obtained an experimental excitation function for 16O+16O using γ-ray spectroscopy. The measurements were performed at center-of-mass energies between 8.28 and 12.25 MeV. The theoretical predictions obtained with a coupled-channel model are consistent with the experimental data. From our analyses, the extrapolated S-factor value at 6.6 MeV, corresponding to the Gamow peak energy for core oxygen burning conditions, is about 3.6 × 1025 MeV barn.Artigo IPEN-doc 09792 Installation of the IMPAC technique in the Pelletron laboratory2002 - RAO, M.N.; OLIVEIRA, J.R.B.; SEALE, W.A.; RIZZUTTO, M.A.; RIBAS, R.V.; ALCANTARA NUNEZ, J.A.; PEREIRA, D.; ADDED, N.; CYBULSKA, E.W.; MEDINA, N.H.; SAXENA, R.N.; CARBONARI, A.W.Artigo IPEN-doc 11167 Implantation of sup(111)In in the Heusler alloys Pdsub(2)MnZ(Z=Sn,Sb,Ge,In) following heavy ion nuclear reactions: measurement of magnetic hyperfine field using PAC spectroscopy2005 - CABRERA PASCA, G.A.; RAO, M.N.; OLIVEIRA, J.R.B.; RIZZUTTO, M.A.; ADDED, N.; SEALE, W.A.; RIBAS, R.V.; MEDINA, N.H.; SAXENA, R.N.; CARBONARI, A.W.Artigo IPEN-doc 11175 Implantation of sup(111)In - probe nuclei with nuclear reactions sup(108)Pd(sup(6,7)Li,xn)sup(111)In using pelletron tandem accelerator: study of local magnetism in Heusler alloys2005 - CABRERA PASCA, G.A.; RAO, M.N.; OLIVEIRA, J.R.B.; RIZZUTTO, M.A.; ADDED, N.; SEALE, W.A.; RIBAS, R.V.; MEDINA, N.H.; SAXENA, R.N.; CARBONARI, A.W.Artigo IPEN-doc 09764 Installation of the IMPAC technique in the Pelletron laboratory2003 - RAO, M.N.; OLIVEIRA, J.R.B.; SEALE, W.A.; RIZZUTTO, M.A.; RIBAS, R.V.; ALCANTARA NUNEZ, J.A.; PEREIRA, D.; ADDED, N.; CYBULSKA, E.W.; MEDINA, N.H.; SAXENA, R.N.; CARBONARI, A.W.
