Abstract

The force of effective interaction between two nonrelativistic electrons inside the strong pulsed laser field of two mutually perpendicular light waves is studied theoretically. The magnetic interaction of effective electron currents makes the main contribution to this force. The magnitude and direction of the electron currents depend on the intensity of the waves. The force of magnetic interaction of effective electron currents may exceed the Coulomb force at long distances. As a result, the effective force of an electron pair’s interaction in the laser fields can be attractive as well as repulsive. Thus, the effect of attraction allows increasing the confinement time of electrons in comparison with the corresponding value without any external fields. The anomalous effect of electron repulsion was predicted. This effect allows electrons (after interaction) to scatter over distances exceeding by an order of magnitude corresponding distances without external fields. The appearance of the effective force of attraction may be experimentally verified in the framework of modern research projects where sources of pulsed laser radiation are used (SLAC, FAIR, XFEL, ELI, XCELS).
