The n-italic independence of these parameters predicted by first-order many-body theory can be explained using basic concepts associated with quantum-defect theory and, if verified by further experimental results, has important consequences for understanding the physics of the electron-atom scattering ...
1. The result show that the important factors what influenced the cross section of radiative recombination of single-electron systems are principal quantum number n, angular quantum number l, atomic core, Z and so on. 利用细致平衡原理,通过光电离对单电子体系的辐射复合截面进行了研究,对计算结果的分...
It explained his absence (缺席)from class the day before. "Dear Mr. McCort, Mikeys grandmother, who is eighty years of age, fell down the stairsfrom too much coffee and I kept Mikey at home to take care of her and his baby sister so I could goto my job. Please excuse Mikey and ...

accompanied by enrichment of W in the bulk. Similar elemental segregation to GBs have also been observed in FeMnNiCoCr MPEA after aging heat treatment in a recent experiment55. This effect can be explained by considering the relative GB energies of the different elements. The current authors hav...
This tendency cannot be well explained only by the Stokes–Einstein law, at least at 0 °C and higher, because the viscosity of liquid water decreases as a function of temperature. Thus, this tendency must have a different origin. Notably, the Langevin-based time correlation function should ...
The total variance explained by the first three principal components was 77.49%. Figure 4 presents the scatter plot in PCA space where each point corresponds to one spectrum and the clusters observed are related to each of the fluorosis severity categories and the control group. Samples of sound...
I had thought that given their name and the lip service to quantum physics the show occasionally gives that they were like the observer whose recording of data/events made it actualize. They'd be sort of the unseen ear that would hear every tree falling in the forest with no one else ...
“Quantum-mechanical model” of electron transfer:In the “quantum-mechanical model”, Lewis (after [74]) claims that contact between nonconductor and conductor leads to the creation of temporary additional donor and/or acceptor states around the contact area. After breaking the contact, the introd...
