我们在文献[1]中设计了一套五个参数的变分波函数用来计算了周期表中前面十个原子的能量,所得结果比过去一些作者用四参数波函数所算得的结果为好。我们在过去计算经验的基础上,另外找到了一套特别简单的解析波函数,其形式为 1s电子: φ_1(r)=N_1e~(-μar), 2s电子: φ_2(r)=N_2[(μr)e~(-μr)-Ne(-μar)], 2p电子: φ_3(r)=N_3(μr)cosθe~(-μr), φ_4(r)=N_4(μr)sinθe~(-i-μr), φ_5(r)=N_5(μr)sinθe~(-i-μr),式中的α与μ为变分参数;N_1,N_2,N_3,N_4,N_5为归一化因子;N为正交化系数。μ可用解析法来决定,因而只有一个参数α要由数值法来决定。我们用这样的波函数算出了第二周期元素的正常态原子和离子(共有八十几个原子态)的各电子的各种能量积分值及总能量值,并确定了波函数的最佳参数值。其结果与五参数波函数的计算结果相比,一般相差在万分之一至千分之一的范围内,并比最近有些作者用一种三参数波函数所算的结果还好。根据这些结果,我们还讨论了Slater近似计算法的可靠程度和适用范围。

In the theory the author uses "coherent superposition" model, i. e. the atomic states are coherent after absorbed photons from different modes of a mode-locked laser. So the final atomic state should be coherently added. The resolvent operator and projector operation are used to derive the operator U. Considering the phase relationship between the modes, the light field are described by multi-mode coherent state. This method can...

A quantum theory for pulse-train from the mode-looked laser has been developed.

So the final atomic state should be coherently added. The resolvent operator and projector operation are used to derive the operator U.

This method can be used to describe the resonant multi-photon processes that the pulse train from the mode locked laser interacting with atoms.

The chemisorbed state of oxygen on a type of Ag0Y zeolite has been studied by temperature programmed desorption (TPD) and electron spin resonance (ESR).The samples were conditioned prior to the data runs by using the OROA cleaning cycle procedure. Which consisted of out-gassing (500℃,1×10-6torr, 2hr) , hydrogen reduction (400℃, 60ml H2/min, 1hr) , out-gassing again (500℃, 1×10~storr, 2 hr), and oxygen adsorption. The adsorption of oxygen on Ag0Y zeolite was carried out under different conditions: (a) from 500℃ to room temperature, and (c) isothermal adsorption at a given temperature. Under these conditions, two adsorbed states a and β are observed in TPD spectra. The peak temperatures of the a and β states are about 120-160 and 233-250℃evolution process is second order indicating an atomic adspecies on silver surface, the activation energy of desorption is found to be 19.69 Kcal/mol. The results obtained from ESR measurements indicate that the atomic adspecies is diamagnetic.Comparing the data of the thermal desorption study with those of ESR study, it may be concluded that the atomic adspecies is Oad.
