【 摘 要 】

Synopsis Due to the correlation between different quantum states, such high-order correlation in the electron-ion resonance recombination can not be resolved in those published state-of-art calculations. Wherever such correlation effect is embodied in the resonant recombination spectroscopy, and were measured on electron beam trap to benchmark theory recently. In this abstract, we theoretically investigate the high-order contribution in the total resonance recombination for carbon-like iron, and it is found to be significant.
