The Relativistic Heavy Ion Collider (RHIC) will accelerate fully stripped ions to beam kinetic energies of 250 (Z/A) GeV/u. For the heaviest nuclei, i.e., {sup 179}Au{sup 79+}, 10{sup 9} ions per bunch will circulate in 57 bunches at a kinetic energy of 100 GeV/u. During bunch crossing, the peripheral interactions of the heavy ions generate a sufficiently large electromagnetic field that spontaneous e{sup +}, e{sup {minus}} pair creations will occur. Up to 10{sup 7} pairs per second are expected at RHIC luminosity values (2 {times} 10{sup 26}cm{sup {minus}2}sec{sup {minus}1}). In addition, a produced electron may be captured by a heavy ion, thus strongly effecting the luminosity lifetime of a heavy ion collider. 12 refs., 4 figs.
