Abstract:
The even-parity autoionizing resonance series 3p5np'[3/2]1,2, 3p5np'[1/2]1, and 3p5nf'[5/2]3 of Ar have been investigated exciting from the two metastable states 3p54s[3/2]2 and 3p54s'[1/2]0 in the photon energy range of 32500-35600 cm-1 with an experimental bandwidth of ~0.1 cm-1. The excitation spectra of the even-parity autoionizing resonance series show typical asymmetric line shapes. New level energies, quantum defects, line profile index and resonance widths, resonance lifetime and reduced widths of the autoionizing resonances are derived by a Fano-type line-shape analysis. The line profile index q and the resonance widths Γ are shown to be approximately proportional to the effective principal quantum number n*. The line separation of the 3p5np' autoionizing resonances is discussed.

摘要:
单光子32500~35600 cm-1能量范围内获得Ar原子亚稳态3p54s[3/2]2和3p54s'[1/2]0向其3p5np'[3/2]1,2,[1/2]1和3p5nf'[5/2]3序列偶宇称自电离态跃迁的共振增强激发光谱,光谱线宽~0.1 cm-1,这些激发谱呈现明显的不对称线形. 根据Fano线形关系对激发谱进行了系统地分析,获得许多新的能级位置、量子亏损、线性因子、共振宽度、共振态寿命和衰减宽度等数据. 基于实验拟合所得的系统参数,发现线形因子和共振宽度相对有效量子数呈线性关系. 另外还分析了3p5np'序列的能级间距.
