对三周期原子（Si， P， S和Cl） x射线吸收光谱中的双电子[数字KL]边共振进行了系统的研究。本文报道了Na[sub - 2]PO[sub - 4]、Graham's盐（Na[sub - 2]O:P[sub - 2]O[sub - 5]）、Na[sub - 4]P[sub - 2]O[sub - 7]、元素S、Na[sub - 2]SO[sub - 3]、K[sub - 2]SO[sub - 4]、CuSO[sub - 4]、Na[sub - 2]S[sub - 2]O[sub - 3]、Na[sub - 2]S[sub - 2]O[sub - 6]、NaClO[sub - 2]、NaClO[sub - 3]、NH[sub - 4]ClO[sub - 4]的实验数据，并结合前人在Si[ital X][sub - 4]、（[ital X]=H、CH[sub - 3]、Br、Cl、F）分子Si[ital KL]边缘的测量结果进行了讨论。这些结果与Ne和Ar中的[数字KL]边缘结构的进一步比较提供了对这些第三周期原子的激励的几乎完整的概述。报道了主要共振的能量和振子强度的汇编，并讨论了能量分裂、强度和能量位置随氧化态和[ital Z]数的主要趋势。
A systematic investigation of double-electron [ital KL]-edge resonances in x-ray-absorption spectra of third-period atoms (Si, P, S, and Cl) is presented. Experimental data on NaH[sub 2]PO[sub 4], Graham's salts (Na[sub 2]O:P[sub 2]O[sub 5]), Na[sub 4]P[sub 2]O[sub 7], elemental S, Na[sub 2]SO[sub 3], K[sub 2]SO[sub 4], CuSO[sub 4], Na[sub 2]S[sub 2]O[sub 3], Na[sub 2]S[sub 2]O[sub 6], NaClO[sub 2], NaClO[sub 3], and NH[sub 4]ClO[sub 4] are reported and discussed in combination with previous measurements at the Si [ital KL] edge of Si[ital X][sub 4], ([ital X]=H,CH[sub 3],Br,Cl,F) molecules. The further comparison of these results with [ital KL]-edge structures in Ne and Ar provides an almost complete overview of these excitations for third-period atoms. A compilation of energies and oscillator strengths for the dominant resonances is reported and the main trends of energy splitting, intensity, and energy position versus oxidation state and [ital Z] number are discussed.
