In the article exact analytical and invariant solutions for both spinless and half-spin relativistic charged particles in crossed constant electric and magnetic fields, when $ H \mathclose{>} E $ have been found. It is shown that in both cases the problem reduces to that of quantum harmonic oscillator.

The strontium atoms in ground states were excited to higher |M|=1 Rydberg states while the laser wavelength and the electric field strength are scanned simultaneously to keep the scaled-energy ε constant. Spectra were recorded for ε=-3.00, -2.50 and -1.88. The experimental Fourier transform recurrence spectra were compared with the hydrogenic closed-orbit calculation. The positions of the experimental recurrence peaks were well coincided with the theory, but the strengths of the peaks were strongly affected by the strontium core effect.
