Resumo
Estudamos a radiação síncrotron (RS) de uma partícula carregada em um campo magnético uniforme e constante com influência do solenóide de Aharonov-Bohm dentro do quadro da teoria quântica relativística. Usando as soluções de Klein-Gordon são calculadas e analisadas as características da radiação espontânea de um fóton, tais como a intensidade, a distribuição angular e a polarização. É também apresentado uma análise detalhada da dependência angular da RS. Estudando as intensidades da RS espectral descobrimos um comportamento inesperado completamente diferente da intensidade da RS total. Essa diferença consiste em que as linhas espectrais possuem uma tendência à desconcentração no plano da órbita quando aumentamos a energia da partícula
Synchrotron radiation of a charged particle in a constant uniform magnetic field and in the presence of the Aharonov-Bohm solenoid field is investigated with reference to the relativistic quantum theory. To start with, the exact solution of the Klein-Gordon equation is found. Using this solution, all the characteristics of one photon spontaneous irradiation, such as intensity, angular distribution and polarization were calculated and analyzed. We have also made a detailed analysis of angular dependence of the synchrotron radiation (SR). By studying the spectral SR-intensities, we have found a new unexpected angular behavior which is completely different from that of the integral SR-intensity. Particularly, for any given synchrotron frequency the spectral ones have the tendency to disperse themselves on the orbit plane, in contrast with the integral SR-intensity, with increasing particle energy
