Phân Tích Chính Xác Năng Lượng Tương Quan Điện Tử Phụ Thuộc Spin cho Các Tính Toán Mật Độ Spin Địa Phương: Phân Tích Phê Phán Dịch bởi AI Chúng tôi đánh giá các hình thức gần đúng khác nhau cho năng lượng tương quan trên mỗi phần tử của khí điện tử đồng nhất có phân cực spin, những hình thức này đã được sử dụng thường xuyên trong các ứng dụng của xấp xỉ mật độ spin địa phương vào chức năng năng lượng trao đổi-tương quan. Bằng cách tính toán lại chính xác năng lượng tương quan RPA như là một hàm của mật độ điện tử và phân cực... ... hiện toàn bộ

INTERNAL ATMOSPHERIC GRAVITY WAVES AT IONOSPHERIC HEIGHTS Irregularities and irregular motions in the upper atmosphere have been detected and studied by a variety of techniques during recent years, but their proper interpretation has yet to be established. It is shown here that many or most of the observational data may be interpreted on the basis of a single physical mechanism, namely, internal atmospheric gravity waves.A comprehensive picture ... ... hiện toàn bộ

INTERACTION OF SLOW ELECTRONS WITH CHEMISORBED OXYGEN Measurements have been made of the effects of low-energy electron bombardment (0–300 ev) on a chemisorbed layer of oxygen on polycrystalline molybdenum. Oxygen is adsorbed in two states at room temperature with approximate heats of adsorption of 60 and 110 kcal/mole, respectively. O+ ions are released from the weakly bound state with a maximum probability of 10... hiện toàn bộ

THE TRANSPORT OF HEAT BETWEEN DISSIMILAR SOLIDS AT LOW TEMPERATURES The resistance offered to the flow of heat by the mismatch of the elastic constants at the interface between two materials has been calculated. It is shown that for a perfectly joined interface the heat flow is proportional to the difference of the fourth powers of the temperature on each side of the interface. Deviations from this temperature dependence are to be expected for rough surfa... ... hiện toàn bộ

Drying of solids wetted by thin liquid films (i) A film of a nonwetting liquid is not stable. If it is thick (thickness e ≥ 1000 Å) it is metastable and evolves via nucleation and growth of a dry spot. If it is thin, it is unstable against spinodal decomposition (amplification of thermal undulations) and breaks into microscopic droplets of size ~e2 /a (a = a molecular size), (ii) A film made with a wetting liquid... ... hiện toàn bộ

ON VOLTERRA'S DISLOCATIONS IN A SEMI-INFINITE ELASTIC MEDIUMIn this paper a Green's function method is developed to deal with the problem of a Volterra dislocation in a semi-infinite elastic medium in such a way that the boundary surface of the medium remains free from stresses. (A Volterra dislocation is here defined as a surface across which the displacement components show a discontinuity of the type Δu = U + Ω ×r, where U and Ω are constant vec... ... hiện toàn bộ

GAMMA-RAY ANGULAR CORRELATIONS FROM ALIGNED NUCLEI PRODUCED BY NUCLEAR REACTIONS Two general procedures for the measurement and analysis of angular correlations of gamma radiations from nuclear reactions are described which have wide applications in nuclear spectroscopy for the determination of spins and gamma-ray multipolarities. Cases can be studied by these methods when the reaction proceeds through a compound state too complex to allow the usual analysis to be mad... ... hiện toàn bộ

SHELL EFFECTS ON THE SPACING OF NUCLEAR LEVELS Recent measurements of resonances in slow neutron total cross sections yield good estimates of the average level spacing, D, in medium and heavy nuclei. These spacings show large variations, by factors of 103 to 105 , in the region of magic numbers of nucleons. There are also variations by smaller factors between nuclei with even and odd numbers of... ... hiện toàn bộ

DISLOCATION DYNAMICS IN DEFORMATION AND RECOVERY Phenomenological equations between dislocation velocity, effective shear stress, temperature, and pressure are presented. It is suggested that the term "activation volume" be properly assigned to the pressure dependence of dislocation velocity. Indirect methods of determining velocity–stress relations are reviewed, and a new method is introduced using the stress–time data in stress relaxa... ... hiện toàn bộ

A METHOD OF DETERMINING THE ELECTRONIC TRANSITION MOMENT FOR DIATOMIC MOLECULES A method is described that will give the variation, as a function of internuclear distance, of the electronic transition moment governing intensities in diatomic molecular band systems. Reliable theoretical results and good experimental intensities are used conjointly to find this variation. Once smoothed, the trend may be replaced into the overlap integrals to give relative vibrational t... ... hiện toàn bộ
