在K边区域的Ne光吸收光谱已被测量到前所未有的能量分辨率。使用从头算方法对结果进行了解释，该方法预测了自然线宽，以及不同$1stackrel{ensuremath{
（3l~nl~6）$跃迁。理论和实验之间的显着的协议，提高了这些内壳层激发态的能量区域，只有电子能量损失光谱被认为是提供准确和高分辨率的数据的光谱表征。
The Ne photoabsorption spectrum in the region of the K edge has been measured with unprecedented energy resolution. The results have been interpreted by using an ab initio method that predicts natural linewidths, as well as relative intensities and positions of the different $1stackrel{ensuremath{
ightarrow}}{s}mathrm{np}$ $(3l~nl~6)$ transitions. The remarkable agreement between theory and experiment improves the spectroscopic characterization of these inner-shell excited states in an energy region where only electron-energy-loss spectroscopies were considered to provide accurate and high-resolution data.
