It has been recognized that e{sup +}e{sup {minus}} pair creation during the collision of intense beams in linear colliders will cause potential background problems for high energy experiments. Detailed knowledge of the angular-momentum spectrum of these low energy pairs is essential to the design of the interaction region. In this paper, we modify the computer code ABEL (Analysis of Beam-beam Effects in Linear colliders) to include the pair creation processes, using the equivalent photon approximation. Special care has been taken on the non-local nature of the virtual photon exchanges. The simulation results are then compared with known analytic formulas, and applied to the next generation colliders such as JLC. 10 refs., 2 figs.
