K. Hencken et al., Bremsstrahlung from electrons and positrons in peripheral relativistic heavy-ion collisions - art. no. 034901, PHYS REV C, 6003(3), 1999, pp. 4901
We study the spectrum of the bremsstrahlung photons coining from the electr
ons and positrons, which are produced in the strong electromagnetic fields
present in peripheral relativistic heavy-ion collisions. We compare differe
nt approaches, making use of the exact pair production cross section in hea
vy-ion collisions as well as the double equivalent photon approximation. [S
