Abstract in Portuguese
O problema da captura de partículas por potenciais singulares esfericamente simétricos é estudado com detalhes no contexto da Mecânica Clássica tanto relativística quanto não-relativística. Os resultados teóricos obtidos no caso não-relativístico são usados para analisar dados recentes obtidos para o caso de potencial inversamente proporcional ao quadrado da distãncia à origem, usando-se átomos "frios" em uma armadilha magnética. No caso relativístico, o problema de Kepler é estudado detalhadamente

Abstract in English
The problem of the capture of a particle by a singular spherical symetric potential is study in the context of the Classical Nonrelativistic and Relativistic Mechanics. The results obtained for the nonrelativisti case are used to discuss the recent experimental data regarding a singular potential inversely proportional to the square of the distance to origin using "cold" atoms in a magnetic trap. For the relativistic case, the capture in a Kepler potential is study in details.
