Abstract

Using the level-crossing technique, magnitude and sign of the tensor polarizability αten of the lowest1 P 1-levels of Ca, Sr, and Ba have been measured by investigating the splitting into Zeeman-sublevels in superimposed homogeneous electric and magnetic fields. The experimental results are: αten/g J =−13.6(3) kHz/(kV/cm)2 for Ca αten/g J =−14.32(15) kHz/(kV/cm)2 for Sr αten/g J =−10.72(10) kHz/(kV/cm)2 for Ba, where theg J -values are approximatelyg J≈1. With greater accuracy the ratios of these constants have been determined by eliminating the electric-field strength measurement: (αten(Sr)/g J (Sr))/(αten(Ca)/g J (Ca))=1.050(8) (αten(Sr)/g J (Sr))/(αten(Ba)/g J (Ba))=1.336(2).

The polarizability constants are discussed with regard to the state vectors of the lowestsp 1 P 1- and3 P 1-levels. The tensor polarizability of the 6s 6p1 P 1-level of Ba I is considered in relation to oscillator strengths of electric dipole transitions to neighbouring levels.
