摘要：

Measurements of oscillator strengths for the principal series of calcium 4s2 S-1(0)-->4snp P-1(1) (11 less-than-or-equal-to n less-than-or-equal-to 25) are reported. The data were acquired using the magneto-optical spectroscopic technique, utilizing the linearly polarized light emitted by the 2.5-GeV electron accelerator, a 7-T superconducting magnet, and a 3-m-high dispersion spectrograph with photographic detection. A quantum-defect plot of the density of the oscillator strengths of discrete transitions yields the photoionization cross section at threshold as 2.04+/-0.20 Mb, in agreement with earlier measurements.
