AI Technical Summary

Problems solved by technology

[0005] At present, many-body coincidence imaging experiments generally use supersonic gas targets. Although high-speed moving gas samples (atoms and molecules) can reduce the temperature of the gas to a certain extent, the thermal motion of gaseous atoms and molecules still exists, which greatly reduces the temperature of the atoms. The energy (momentum) resolution of molecular imaging experiments makes it difficult to distinguish the quantum state in the energy representation (momentum distribution), blurring the internal physical image

[0006] In addition, other frontier scientific issues in atomic and molecular physics, such as highly excited state quantum chaos induced by electron-electron correlation in many-body dynamics, double-electron ionization correlation entanglement, and the internal physical mechanism of attosecond high-order harmonic generation, are also limited by the current resolution. and cannot be completely resolved
