摘　　要：通过同步改变激光扫描波长和外加电场大小 ,保持标度能为常量 ,将Sr原子从基态激发到 |M | =1的激发态 ,得到了标度能ε =- 3 .0 0 ,- 2 .5 0 ,- 1.88时的常数标度能谱 .实验傅里叶变换回归谱与氢原子闭合轨道理论计算进行了比较 ,峰值位置符合较好 。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.
