Abstract
Photon production cross section in heavy-ion collisions is estimated by employing the elementary process of proton-neutron bremsstrahlung in a Boltzmann-Uehling-Uhlenbeck model. With taking the electromagnetic field into account for simulating the reactions, the magnetic effects are considered in different impact parameter regions for the collisions of 14N + 208Pb at incident energy of 40 MeV/nucleon in the laboratory system. We investigated the energy spectra, production rates, and the polar angular distributions of photons. In particular, the directed flow $ v_{1}$ and elliptic flow $ v_{2}$ are extracted for both photons and free nucleons. In contrast with unaffected nucleon flows by the magnetic field, photon flows do display magnetic field effect.
