碘和溴分别由分子碘和溴的激光诱导解离产生的原子在4d-> np（n> 5）和3d-> np（n> 4）激发区被光激发。总离子产额谱显示许多线的位置和扩展归因于开壳效应。本文研究了碘原子4d → 6p跃迁的衰变。这种共振的弛豫主要是共振俄歇过程，伴随着强烈的振动过程。与原子碘中4d-> 5p共振的衰变和氙中4d-> 6p共振的衰变的比较表明，内壳层共振的衰变机制对核电子被提升进入的轨道的性质具有很强的敏感性。
Iodine and bromine atoms produced by the laser-induced dissociation of, respectively, molecular iodine and bromine have been photoexcited in the region of the 4d --> np (n > 5) and 3d --> np (n > 4) excitations. Total ion-yield spectra show numerous lines whose positions and extensions are attributed to open-shell effects. The decay of the 4d --> 6p transition in atomic iodine has been investigated. The relaxation of this resonance is dominated by resonant Auger processes accompanied by strong shake processes. The comparison with the decay of the 4d --> 5p resonances in atomic iodine and with the 4d --> 6p resonances in xenon shows a strong sensitivity of the decay mechanisms of inner-shell resonances to the nature of the orbital into which the core electron has been promoted.
