High-intensity x rays generated by an x-ray free-electron laser can induce multiple sequences of one-photon ionization and accompanying decay processes in atoms and often produce highly-charged atomic ions. Considering individual quantum states during these processes provides preciser information about the multiphoton ionization dynamics than the common configuration-based approach. However, to perform the extremely huge-size state-resolved calculations for heavy atoms, an embedded machine learning model is inevitable.
