Study of Ba 6snk Rydberg states in electric field

The autoionization detection is employed to measure the Stark spectra of Ba 6snk Stark states with n from 13 to 15. The Stark maps with M=0 and |M|=1 can be selectively excited by two lasers with different combinations of polarization under different strengths of electric fields. General features of...

Description
Summary:The autoionization detection is employed to measure the Stark spectra of Ba 6snk Stark states with n from 13 to 15. The Stark maps with M=0 and |M|=1 can be selectively excited by two lasers with different combinations of polarization under different strengths of electric fields. General features of Ba Stark states observed in the experiment are discussed in detail, and the comparisons between M=0 and |M|=1 cases are made. Theoretical calculations based on the perturbation theory are performed to simulate the corresponding experiments, results of which are satisfactory.
