正电子-电子碰撞可能会产生巨大的交叉磁场台阶。在恒定磁场(例如，1T)内，正电子和电子之间的碰撞可以导致在连续的撞击参数范围内穿过磁场的相关漂移。在此范围内，通过计算机模拟观察到的漂移距离比同电荷碰撞的漂移距离大几个数量级。在这个范围之外，碰撞行为类似于具有相同电荷的粒子之间的碰撞行为。使用质心和相对坐标对这一现象进行的理论分析提供了关于巨型交叉磁场台阶发生的见解。
Giant cross-magnetic-field steps can occur as a result of positron-electron collisions. Within a constant magnetic field (e.g., 1 T), a collision between a positron and an electron can result in a correlated drift across the magnetic field for a continuous range of impact parameters. Within this range, drift distances orders of magnitude larger than that associated with like-charge collisions were observed by computer simulation. Outside of this range, the collisional behavior is similar to that for collisions between particles with the same charge. A theoretical analysis of the phenomenon using center-of-mass and relative coordinates provides insights regarding the occurrence of giant cross-magnetic-field steps.
