Abstract

The main objective of the project is to investigate the dependence of the several parameters thatcan characterize the nuclear reaction cross sections in the framework of different models using theinformation entropy concept. During the calculation and analysis of quantum nuclear states, thecritical points of stability in the configuration of informational entropy will be computed. Thesepoints correspond to the experimental parameters, which are obtained during the fitting procedure.This new approach is crucial and important for the understanding of the stability of quantum statesin the study of deep inelastic scattering processes. The other aim of the present project is tostudy the mechanism of the nuclear reactions based on the method of induced activity for studyingnuclear reactions within the Centro de CiÆencias Naturais e Humanas (CCNH) da Universidade Federaldo ABC (UFABC). Using this method one can investigate different features of the reactions,including the reaction mechanism, as well as such features as a probability that the reaction occursand the various characteristics of the charge and mass distributions. Within the induced activitymethod one can estimate the average initial angular momentum of the reaction residues by usingthe statistical model of Huizenga-Vandenbosch. To use the CRISP model in the study of nuclearreactions in order to investigate the relevant aspects of the reaction dynamics and their consequencesto the final reaction product. As well as to get the knowledge of nuclear processes for the study ofdifferent nuclear reaction applications. We already provided the new data of the cross sections forthe Experimental Nuclear Reaction Data (EXFOR), which have been obtained during the experimentsimplemented within the grants Auxílio à Pesquisa - Regular 2016/18902-9, BEPE FAPESP2013/01754-9, 2014/00284-1 and FAPESP 2011/00314-0.
