对于Yb Ⅰ和Yb Ⅱ的36条最强谱线，在7700- 2200埃区间和激发电子能量从阈值到300 eV的范围内，首次研究了有效截面和激发函数。所观察到的线的条件下的一个和两个电子激发的6s和4f原子电子。谱线激发最大值处的截面幅值在10/sup-16/-10/sup-19/-cm/sup 2/区间内。
For the thirty-six most intense spectral lines of Yb I and Yb II, the effective cross sections and excitation functions are first studied within the 7700--2200-A interval and within the range of exciting electron energies from threshold to 300 eV. The observed lines are conditioned by the one- and two-electron excitation of the 6s and 4f atomic electrons. The cross section magnitudes at the maximum of the spectral line excitation are found to be within the 10/sup -16/--10/sup 19/-cm/sup 2/ interval.
