本文建立了一个相对论推广的半经典理论，即在具有线性、圆偏振和椭圆偏振的高强度电磁波场中原子和离子的隧穿和多光子电离。计算了绝热性参数γ为任意值时电离几率的指数因子。在低频激光辐射的情况下，一个渐近精确的公式推导出的s原子水平的电离率，包括库仑，自旋和绝热修正和指前因子。
A relativistic generalization of the semiclassical theory of tunneling and multiphoton ionization of atoms and ions in the field of a high-intensity electromagnetic wave with linear, circular, and elliptic polarization is constructed. The exponential factor in the ionization probability is calculated for arbitrary values of adiabaticity parameter γ. In the case of low-frequency laser radiation, an asymptotically exact formula is derived for the ionization rate of the s atomic level, including the Coulomb, spin, and adiabatic corrections and the preexponential factor.
