使用高分辨率电子能谱研究了 95 MeV/核子 Ar{sup 18+} 射弹在 Li 中产生双 K 壳空位。发现两个 K 空位主要通过电离和激发产生，从而在空心 Li{sup +} 中产生激发态。 2s{sup 2}thinsp{sup 1}S 和 2s3sthinsp{sup 3}S 配置的强线强度为电子-电子相互作用提供了光谱识别。 2s3sthinsp{sup 3}S 态的产生，其强度大于 2s{sup 2}thinsp{sup 1}S 态，归因于涉及关联的三电子跃迁。 {版权} {ital 1999} {ital 美国物理学会 }
Double-K -shell-vacancy production in Li by 95 MeV/nucleon Ar{sup 18+} projectiles was investigated using high-resolution electron spectroscopy. The two K vacancies are found to come about mainly by ionization and excitation, giving rise to excited states in hollow Li{sup +} . Strong line intensities from the 2s{sup 2}thinsp{sup 1}S and 2s3sthinsp{sup 3}S configurations provide spectral identification for the electron-electron interaction. Production of the 2s3sthinsp{sup 3}S state, with an intensity greater than that for 2s{sup 2}thinsp{sup 1}S , is attributed to a three-electron transition involving correlation. {copyright} {ital 1999} {ital The American Physical Society }
