New resonances in ${}^{11}C$ above the ${}^{10}B + p$ threshold investigated by inverse kinematic resonant scattering
by Gurpreet Kaur, V. Guimarães, J. C. Zamora, M. Assunção, J. Alcantara-Nunez, A. L. de Lara, E. O. N. Zevallos, J. B. Ribeiro, R. Lichtenthäler, K. C. C. Pires, et al.
The spectroscopy of ${}^{11}C$ has been investigated by the resonant scattering of ${}^{10}B + p$ with the thick target inverse kinematic method. The ${}^{1}H ({}^{10}B, p) {}^{10}B$ reaction was measured at $θ_{c . m .} = 180^{\circ}, 170^{\circ}, 160^{\circ}, 150^{\circ}$ , and $140^{\circ}$ using a 35.93 MeV ${}^{10}B$ beam. Resonances in ${}^{11}C$ between the excitation energy of 9.6 and 11.8 MeV are observed. The excitation functions are compared with previous data using thin target direct kinematics measurements. A multichannel $R$ -matrix calculation under the kinematics assumption of resonant elastic scattering is performed and the resonant parameters, such as the resonant energy $E_{x}$ , the spin-parity $J^{π}$ , and the proton-decay partial width $Γ_{p}$ are extracted.

Ciência e reparação: 100 anos das Contribuições de Lise Meitner para o Efeito Auger
by V. Morcelle, R.M.S. Ferreira, A.C.F. Santos
Há 100 anos, a física austríaca Lise Meitner (1878–1968) descobriu um efeito amplamente utilizado na atualidade para analisar superfícies e estudar a dinâmica da dissociação de moléculas isoladas, o Efeito Auger, estudado em disciplinas avançadas na graduação em Física. Neste trabalho, revisaremos alguns aspectos da história de Lise Meitner e da física do efeito, que até hoje leva o nome do físico francês Pierre Auger (1899–1993), que descobriu o mesmo fenômeno cerca de dois anos depois. Assim como outros pesquisadores, endossamos a importância de renomear este efeito e reconhecer as contribuições de ambos os cientistas.

Evidence of the effect of strong stripping channels on the dynamics of the ${}^{8}{Li} + {}^{58}{Ni}$ reaction
by O. C. B. Santos, R. Lichtenthäler, K. C. C. Pires, U. Umbelino, E. O. N. Zevallos, A. L. de Lara, A. S. Serra, V. Scarduelli, J. Alcántara-Núñez, V. Guimarães, et al.
The ${}^{8}{Li} + {}^{58}{Ni}$ collision is investigated at 23.9, 26.1, 28.7, and 30 MeV bombarding energies. Quasielastic angular distributions and the singles ${}^{7}{Li}$ angular and energy distributions are presented. Coupled-reaction channels (CRC) calculations, which include the coupling of the elastic channel to ${}^{59}{Ni} = {}^{58}{Ni} + n$ states above and below the neutron threshold, provide a simultaneous description of the quasielastic and transfer distributions and evidence the strong effect of the one-neutron transfer/breakup channels on the quasielastic scattering. The ${}^{7}{Li}$ angular and energy distributions have been also successfully analyzed combining the continuum discretized coupled channels (CDCC) method, for the elastic breakup, and the IAV model of Ichimura, Austern, and Vincent [ Phys. Rev. C 32, 431 (1985)], for the nonelastic breakup. These calculations indicate that most of the ${}^{7}{Li}$ yields are due to nonelastic breakup contributions (transfer), whereas elastic breakup plays a minor role.

Study Of High Lying Resonances In 9Be By The Measurement Of (p,p), (p,α) And (p,d) Reactions
by Alinka Lepine-Szily, Erich Leistenschneider, Pierre Descouvemont, Djalma R. Mendes, Rubens Lichtenthaler, Marcos Alvarez, Ruben Pampa, Pedro N. de Faria, Kelly Cc. Pires, Valdir Scarduelli, et al.
The (p, p), (p, a) and (p, d) reactions on 8Li were measured at low energies. The experiment was performed using a thick [CH2]n target and a radioactive 8Li beam available at the RIBRAS facility of São Paulo . This experiment represents an upgrade of a previous experiment, where only the 8Li(p,a)5He cross section was measured. High lying resonances of 9Be, which are still uncertain, could be studied in this way. The detection of several reaction channels allows a reliable determination of the resonance parameters, such as energy, width and spin-parity. In the deuteron channel we could observe the same resonance decaying to d+7Ligs and to d+7Li∗. The properties of the resonances are determined by a R-matrix analysis, which provides evidence for a significant clustering as well in the (p, a) as in the (p, d) channels. The experimental data and the multi-channel R-matrix analysis will be presented.

Elastic and inelastic scattering for the ${}^{11}B + {}^{58}{Ni}$ system: Target and projectile reorientation effects
by N. N. Deshmukh, V. Guimarães, E. Crema, D. Abriola, A. Arazi, E. de Barbará, O. A. Capurro, M. A. Cardona, J. Gallardo, D. Hojman, et al.
Full angular distributions for elastic and inelastic scattering of ${}^{11}B$ on ${}^{58}{Ni}$ have been measured at different bombarding energies around the Coulomb barrier. Measurement and analysis with coupled-channel calculations have been performed for the first time for a system with the tightly bound ${}^{11}B$ as projectile on a medium mass target. In these calculations, the real part of the interaction potential between nuclei was represented by a parameter-free double-folding potential. To avoid the use of an imaginary potential at the surface, several inelastic transitions of the projectile and the target have been included in the coupling matrix. The result of these coupled-channel calculations are in very good agreement with all experimental angular distributions. The most important result was the striking influence on the reaction mechanism of the ground-state-spin reorientation of the ${}^{11}B$ nuclei.

Recent results on reactions with radioactive beams at RIBRAS (Radioactive Ion Beams in Brazil)
by A Lépine-Szily, R Lichtenthäler, V Guimarães, A Arazi, A Barioni, E A Benjamim, P N de Faria, P Descouvemont, L R Gasques, Leistenschneider, et al.
We present a quick description of RIBRAS (Radioactive Ion beams in Brazil), which is a superconducting double solenoid system, installed at the Pelletron Laboratory of the University of São Paulo and extends the capabilities of the original Pelletron Tandem Accelerator of 8MV terminal voltage (8UD) by producing secondary beams of unstable nuclei. The experimental program of the RIBRAS covers the study of elastic and inelastic scattering with the objective to study the interaction potential and the reaction mechanisms between weakly bound (RIB) and halo (⁶He and ⁸B) projectiles on light, medium and heavy mass targets. With highly purified beams, the study of resonant elastic scattering and resonant transfer reactions, using inverse kinematics and thick targets, have also been included in our recent experimental program.
