116 Fe I线的振子强度，从组合的激光诱导荧光（LIF）技术和分支比从傅里叶变换和光栅光谱测量的寿命。选择了激发能量范围从25000到54000 cm −1的谱线，以扩大太阳和恒星丰度研究的合适谱线集。f值的总体不确定性通常在7%至12%之间，最多为29%。数据与文献值进行了比较。本研究是最近发表的Fe I测量结果的继续
Oscillator strengths of 116 Fe I lines were obtained from a combination of lifetimes measured with the laser induced fluorescence (LIF) technique and branching ratios obtained from Fourier-transform and grating spectra. Lines covering a range of excitation energies from 25 000 to 54 000 cm −1 were chosen to enlarge the set of suitable lines for solar and stellar abundance studies. The overall uncertainties of the f-values are typically between 7% and 12%, and 29% at the most. The data are compared with literature values. The present study is a continuation of recently published Fe I measurements
