本文给出了含时Dirac方程的一个精确解。精确的过渡概率，相当于那些将在一个未截断的基础耦合通道计算，提出。精确的束缚电子-正电子对生产概率计算大多小于那些计算与相同的潜在的微扰理论在影响参数足够小的差异发生。{版权} {美国物理学会}
An exact solution of the time-dependent Dirac equation for ionization and pair production induced by ultrarelativistic heavy ion collisions is presented. Exact transition probabilities, equivalent to those that would be obtained in an untruncated basis coupled channels calculation, are presented. Exact bound-electron positron pair production probabilities are calculated to be mostly smaller than those calculated with the same potential in perturbation theory at impact parameters small enough for differences to occur. {copyright} {ital 1997} {ital The American Physical Society}
