Transition from magnetic to electric-field (F∥B) dominated spectra of barium at threshold
Abstract
Using high-resolution laser spectroscopy, we have studied the distribution of oscillator strength in parallel magnetic (B=970 G) and electric (0<=F<=18 V/cm) fields in the vicinity of the zero-field threshold of Ba. The Fourier transforms of the spectra exhibit transitions from quasi-Landau resonances to electric-field-induced oscillations. The transitions were followed by calculating classical trajectories and Poincaré surfaces of section.
