  ionized atom
The energy spectrum is entirely discrete, including states which correspond to the ionized atom.
      
The Born-Haber cycle relating the Auger decay energy of an adsorbed core-ionized atom to that of a similar free atom is also presented.
      
Depending on the relative magnitudes of the work function of the substrate and the ionization potential of the core-ionized atom, the screening charge may reside either in the substrate or on the adsorbate atom itself.
      
The effect is operative both for the nucleus of a fully ionized atom and for the nucleus of a neutral atom.
      
At atomic distances, these fields differ only slightly from the corresponding fields of an ionized atom.
      


Atoms are first excited and then ionized by two different laser pulgeg, respectively. When the energy per pulse of the ionizing laser is near 1J/cm2, the ionization is saturated. By measuring the relative number of ionized atoms versus the ionizing laser energy, we can easily obtain the photoionization cross section for the excited state of the atoms. The ionizing laser pulse is delayed until the exciting laser pulse is stopped. It aims to eliminate the contribution of the ionization...

Atoms are first excited and then ionized by two different laser pulgeg, respectively. When the energy per pulse of the ionizing laser is near 1J/cm2, the ionization is saturated. By measuring the relative number of ionized atoms versus the ionizing laser energy, we can easily obtain the photoionization cross section for the excited state of the atoms. The ionizing laser pulse is delayed until the exciting laser pulse is stopped. It aims to eliminate the contribution of the ionization signal produced by the exciting laser and to avoid the Stark shift produced by the ionizing laser. The photoionization

用两束脉冲激光,一束使原子共振激发,另一束使激发态原子电离,当电离光脉冲能量约达1J/cm~2时,可使电离饱和.测量被电离原子数的相对大小与电离光脉冲能量之间的函数关系,可以方便地得出原子激发态的光电离截面.延迟电离光至激发光脉冲结束后到达作用区,可以修正激发光对电离的贡献,并避免电离光引起的Stark位移对共振激发的影响.应用共振激发延迟电离方法测定了Cs原子7~2P_(3/2)态的光(λ=5320(?))电离截面,测量值σ_I=6.5×10~(-18)cm~2与Manson的计算值非常接近.

We have established the non-relativistic and relativistic atomic configuration interaction methods to calculate excitation energies of low excited states as well as radiative transition probabilities for allowed and forbidden transitions. In order to check our computer codes, we have calculated the excitation energies for N=2 states and the corresponding radiative transition rates for the atomic helium. The results of our non-relativistic and relativistic calculations agree with each other. The excitation energies...

We have established the non-relativistic and relativistic atomic configuration interaction methods to calculate excitation energies of low excited states as well as radiative transition probabilities for allowed and forbidden transitions. In order to check our computer codes, we have calculated the excitation energies for N=2 states and the corresponding radiative transition rates for the atomic helium. The results of our non-relativistic and relativistic calculations agree with each other. The excitation energies are accurate within a few thousandths, the corresponding radiative transition probabilities within a few percents. Our methods can be readily applied to other atoms as well as ionized atoms.

我们建立的非相对论性和相对论性原子组态相互作用理论计算方法可用来计算低度激发态的激发能量和辐射跃迁几率(包括允许跃迁和禁戒跃迁)。为了检查我们的计算程序,分别用两种方法计算了氦原子N=2激发态的激发能和相应的辐射跃迁几率。结果表明:非相对论性理论和相对论性理论计算结果基本一致。原子激发能量的精度为千分之几,振子强度的精度为百分之几。上述原子组态相互作用理论方法可用于计算任何原子或离化态原子。

A low inductance three-electrode vacuum spark source for generating spectra of highly ionized atoms fed by a 30-kv, 1.43-μF capacitor has been constructed and in operation for some time. The source was used to produce the radiation, which was analyzed in a vacuum ultraviolet spectr-ophotometer (SGV-50) with a concave grating set for normal incidence. By use of spark between electrodes made of materials containing elements under investigation, we have recorded lines of multiply ionized C, Al and Ti...

A low inductance three-electrode vacuum spark source for generating spectra of highly ionized atoms fed by a 30-kv, 1.43-μF capacitor has been constructed and in operation for some time. The source was used to produce the radiation, which was analyzed in a vacuum ultraviolet spectr-ophotometer (SGV-50) with a concave grating set for normal incidence. By use of spark between electrodes made of materials containing elements under investigation, we have recorded lines of multiply ionized C, Al and Ti in the region 200-2000A. Majority (174 in number) of the emission lines of carbon, sixty-eight lines of oxygen, forty-four lines of nitrogen, twenty-four lines of aluminium and twenty lines of titanium have been identified.
