The charge dependence of the effective nucleon-nucleon interaction in asymmetric nuclear matter is investigated within the framework of the lowest-order Brueckner theory. The reaction matrix is calculated self-consistently from the Reid soft-core potential at the normal nuclear density. Even at alpha ...
Effective nuclear charge (Zeff) is the “positive charge” felt by an electron. 参考答案:对 点击查看答案&解析
Nuclear charge radii of the even sulphur isotopes 32S, 34S, and 36S and of 31P using muonic atoms. Energies of muonic x rays of the Lyman series of the even sulphur isotopes /sup 32/S, /sup 34/S, and /sup 36/S and of natural phosphorus have been determin... Schaller,Barandao,...
fractional nuclear chargeQTAIMThe so called cis〆ffect, in which the cis form of an ethylenic compound is more stable than its trans﹊somer, is a good example of a rare phenomenon described only for a few isomeric pairs. In this work, a novel approach to the study of this rare effect ...
Rock weathering is a key process in global elemental cycling. Life participates in this process with tangible consequences observed from the mineral interface to the planetary scale. Multiple lines of evidence show that microorganisms may play a pivotal—yet overlooked—role in weathering. This topic ...
The improvement of the photocatalytic effect of POCN0.01 was attributed to its narrow bandgap, effective charge separation and enhanced specific surface area. This is the first report to describe the use of phosphorus doping to promote the generation of reactive oxygen species (ROS). ROS scavenging...
In the same time, the quantum-tunneling mechanism would enable these star-core-synthesized energetic neutrons of the highest energy level to penetrate into the nuclei shells of the atoms lie within the very center of the planetary embryos, which could create a group of ultra-heavy mega-nuclear ...
neutral, meaning that they have no overall charge. He reasoned that there must be some positive charge in atoms that cancels out the negative charge of the electrons. He also followed the work of William Thomson (Lord Kelvin), who had proposed a model of a positive sphere atom a year ...
(PDB ID 2IS6) transferred by superpositioning of the UvrD NTPase domains on HelD, illustrating clashes with the nucleotide. ADP-Mg2F3shown as sticks and colored by atom type; carbon, beige; nitrogen, blue, oxygen, red, phosphorus, orange; magnesium ions, green; fluoride ions, light blue....
A drawback of this approach is that the parameter set is not unique, and higher-order nuclear matter properties at saturation cannot be unambiguously predicted. Moreover, many parameters of the effective force become strongly correlated in the course of their fixation. Of late, another effective ...
