E + e - Pair production in ultrarelativistic heavy-ion collisions at intermediate impact parameters
Using the semiclassical Green's function in the Coulomb field, we analyze the probabilities of single and multiple e + e - pair production at a fixed impact parameter b between colliding ultrarelativistic heavy nuclei. We perform calculations in the Born approximation with respect to the parameter Z Bα and exactly in Z Aα, where Z A and Z B are the charge numbers of the corresponding nuclei. We also obtain the approximate formulas for the probabilities valid for Z Aα, Z Bα ≲ 1. © Nauka/Interperiodica 2007.
