论文摘要
在两个重离子的碰撞中，来自库仑场的强烈排斥足以产生真空波动的$ e^+e^ - $对。能量由离子的动能和生产点的库仑相互作用提供。例如，如果电子位于沿\ emph {z}轴移动的两个离子的质量（c.m.）中心，并且正电子位于距离电子的距离\ emph {x}处，则离子可以彼此相互加速，因为库仑屏障被电子的存在降低。这种筛选导致碰撞离子的动能增加，并可能导致光离子高于绝热极限的融合概率的增加。
In the collision of two heavy ions, the strong repulsion coming from the Coulomb field is enough to produce $e^+e^-$ pair(s) from vacuum fluctuations. The energy is provided by the kinetic energy of the ions and the Coulomb interaction at the production point. If, for instance, the electron is located at the center of mass (C.M.) of the two ions moving along the \emph{z}-axis, and the positron is at a distance \emph{x} from the electron, the ions can be accelerated towards each other since the Coulomb barrier is lowered by the presence of the electron. This screening results in an increase in the kinetic energy of the colliding ions and may result in an increase in the fusion probability of light ions above the adiabatic limit.
