1. Bremsstrahlung de elétrons no microtron do IFUSP: medidas, simulação e proposta de aplicação ao estudo da ressonância fluorescente nuclear / Electron Bremssthahlung in the IFUSP microton: measurements, simulation and proposal for a nuclear resonance fluorescence observation setup
The results of the first experiments carried out in the new electron accelerator of the Linear Accelerator Laboratory (LAL) of the Physics Institute of Universidade de São Paulo are reported here. A 1.9 MeV beam line, which allows the use of the injector beam for experimental physics, was added to the original accelerator design. Electron bremsstrahlung spe

2. Small-x physics at coherent pA/AA interactions at LHC
We report on our recent investigations in photonuclear production of heavy quarks and vector mesons in ultraperipheral collisions at nucleus-nucleus and proton-nucleus reactions. They are initiated by quasi-real photons coming from one of the nuclei or hadron in interactions taking place at large impact parameter. We focus on the role played by the high ener

3. The Intranuclear Cascade Model MCMC and its Applications for the Quasi-Deuteron Mechanism and Pion Photoproduction at Intermediate and High Energies / O modelo de cascata intranuclear MCMC e aplicações para o mecanismo do quase-dêuteron e a fotoprodução de pions em energias intermediárias e altas
O Presente trabalho propôs o estudo de reações fotonucleares e fotoprodução de pions em energias intermediárias e altas usando o modelo de cascata intranuclear MCMC para a fase rápida de reação e outro algoritmo de Monte Carlo para descrever o processo de decaimento do núcleo composto via evaporação de partículas e fissão nuclear. Dentre as pri

4. Hot hypernucleus formation in high-energy photonuclear reactions
The probability of a compound residual hot hypernucleus formation at the end of pre-equilibrium phase of high energy photonuclear reactions is calculated with a time dependent Monte Carlo Multicollisional Cascade (MCMC) approach. The emission of hadrons during the rapid phase of the reaction is discussed and characteristics of the residual nucleus are obtain

5. New approach to nuclear photofission reactions above 0.15 GeV
A simple approach to evaluate nuclear photofissilities at energies above the pion photoproduction threshold has been developed. It is based on the current, two-step model for intermediate-energy photonuclear reactions, i.e. a photon-induced intranuclear cascade followed by a fission-evaporation competition process for the excited, post-cascade residual nucle
