Abstract

With taking electromagnetic field into account for the transport model of Boltzmann-Uehling-Uhlenbeck, electromagnetic effects are studied for \(^{208}{\hbox{Pb}}\,+\,^{208}{\hbox{Pb}}\) collisions around 100A MeV. Electromagnetic field evolution during the collisions was estimated. It was found that the electric field has an obvious effect on the transverse momentum (\(p_{\text{T}}\)) spectra of nucleons during heavy ion collisions, and leads to different minimum position for the peak of \(p_{\text{T}}\) spectra of nucleons versus beam energy when the electric field is switched on. For the magnetic field, it affects the z-axis direction distributions of nucleons for central heavy ion collisions at lower energy.
