ABSTRACT
High-resolution atomic-beam laser spectroscopy has been performed to study Stark effect of Ba atom. Stark spectra have been observed at various electric fields for Ba highly excited states. The scalar polarizability of the transition from 6s5d 3D2 to 5d6p 3F3 at 728.0 nm and the tensor polarizability of the 3F3 level have been determined for the first time, to be αs = 89.8(12) kHz/(kV/cm)2 and αt = 133.7(20) kHz/(kV/cm)2, respectively.
