Calculations of the photoionization cross sections of the ground states of the superheavy atoms No (Z = 102), Cn (Z = 112) and Og (Z = 118) have been performed using fully relativistic methodologies. The photoionization cross sections are dominated by interchannel coupling, in all cases, over a broad energy range including both outer and inner shells.

超重原子的光电离：相关和相对论效应

已经使用完全相对论方法对超重原子No（Z = 102），Cn（Z = 112）和Og（Z = 118）的基态的光电离截面进行了计算。在所有情况下，包括外部和内部壳层在内的广泛能量范围内，光电离横截面均以通道间耦合为主导。
