摘要

在考虑核间轴旋转影响的情况下，提出了一种计算超出单极子近似的重核碰撞中电子-正电子对产生概率的方法。在旋转和惯性两个参照系中考虑了旋转的影响。对铀核对称碰撞的计算表明，对于小碰撞参数的低能碰撞，旋转耦合对产生对概率的影响可以忽略不计。

Influence of the Internuclear Axis Rotation on the Probabilities of Pair Production in Collisions of Heavy Nuclei

A method has been developed for calculating the probabilities of electron-positron pair-production in collisions of heavy nuclei beyond monopole approximation, taking into account the effects of internuclear axis rotation. The effects of rotation were considered in two frames of reference: rotating and inertial. Calculations for symmetric collisions of uranium nuclei show that the effect of the rotational coupling on the probabilities of pair production is negligible for low-energy collisions with small impact parameters.
