Abstract: Choosing the polarization of the laser,changing the wavelength of the excitation laser and the strength of an external electric field synchronously to keep scal edenergy constant,we have measured M=0 constant scaledenergy absorption spectra of barium Rydberg atoms at scaledenergy ε=-300.Fourier transfor med recurrence spectra were compared with the closedorbit calculation for hydr ogen atom in the uniform approximation.The positions of experimental recurrence peaks fit well the theoretical ones,but the peak strengths differ remarkably,esp ecially in the region of scaledaction larger than 5.This may indicate a large effect of the barium core and the electron correlation on the electron dynamics.
