| 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=-3.00,-2.50,-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,峰值强度则受Sr原子实效应影响较大.

| Abstract: | 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. |
