Improved calculation of total cross section for pair production by relativistic heavy ions

Journal Article · · Phys. Rev. A; (United States)
A calculation of the total cross section for direct electron-positron pair production by heavy ions is described. It combines the use of the Weizsaecker-Williams method for low-energy transfers and existing calculations for high-energy transfers. Higher-order corrections to the total cross section are calculated based on the Weizsaecker-Williams method and existing results for pair production by photons.
