1. "Implementação da técnica de correlações angulares perturbadas no laboratório Pelletron para estudo de estruturas e interações de biomoléculas" / Implementation of The Perturbed Angular Correlations Technique at The Pelletron Laboratory for the Study of Biomolecules Structures and Interactions
This work is related to the implementation of a perturbed angular correlation (PAC) spectrometer at the University of São Paulo Pelletron Laboratory. The spectrometer consists of 6 cylindrical BaF$_2$ scintillator detectors, with 3 inches diameter and 6 inches length and a multiparameter CAMAC data acquisition system. Different from usual, the gamma ray ene

2. Caracterização da microestrutura de materiais porosos por microtomografia de raios x e transmissão de raios gama
This work presents the application of the X-Ray Microtomography and Gamma Ray Transmission techniques for the microstructure characterization of different kinds of materials. Total porosity, pore size distribution and the two point correlation functions were measured. The two point correlation function, which allows the reconstruction of 3D models, was carri

3. Efficiency to HPGe detector to photons in the 4-10 MeV range / "Eficiência de detetores HPGe para fótons de 4 a 10 MeV"
Um detetor HPGe foi calibrado na faixa de energia 4 a 10 MeV usando fótons provenientes do decaimento do produto da reação 27Al(p, g)28Si em linha, observando as ressonâncias com prótons de energias 992 e 1317 keV. Foram feitas calibrações de energia e eficiência de deteção de fótons e foi analisada a dependência da largura a meia altura dos pico

4. Gamma-ray tracking with segmented HPGe detectors
This paper gives a brief overview of the technical progress that can be achieved with the newly available segmented HPGe detectors. Gamma-ray tracking detectors are a new generation of HPGe detectors which are currently being developed to improve significantly the efficiency and resolving power of the 4pi germanium detectors arrays for high-precision gamma-r
