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
Tập 58 Số 8 - Trang 1200-1211 - 1980
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 spin, c...

INTERNAL ATMOSPHERIC GRAVITY WAVES AT IONOSPHERIC HEIGHTS
Tập 38 Số 11 - Trang 1441-1481 - 1960
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 is
envisa...
INTERACTION OF SLOW ELECTRONS WITH CHEMISORBED OXYGEN
Tập 42 Số 5 - Trang 886-905 - 1964
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 10−5 ion/electron at an
electron energy...
THE TRANSPORT OF HEAT BETWEEN DISSIMILAR SOLIDS AT LOW TEMPERATURES
Tập 37 Số 3 - Trang 334-349 - 1959
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 surfaces and f...
Drying of solids wetted by thin liquid films
Tập 68 Số 9 - Trang 1084-1088 - 1990
(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 is
metastable and tends to sh...
ON VOLTERRA'S DISLOCATIONS IN A SEMI-INFINITE ELASTIC MEDIUM
Tập 36 Số 2 - Trang 192-205 - 1958
In 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 vectors.) I...
GAMMA-RAY ANGULAR CORRELATIONS FROM ALIGNED NUCLEI PRODUCED BY NUCLEAR REACTIONS
Tập 39 Số 6 - Trang 788-824 - 1961
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 made, for ex...
SHELL EFFECTS ON THE SPACING OF NUCLEAR LEVELS
Tập 34 Số 8 - Trang 804-829 - 1956
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 protons or neutrons. The even–odd effect is
a co-o...
DISLOCATION DYNAMICS IN DEFORMATION AND RECOVERY
Tập 45 Số 2 - Trang 493-509 - 1967
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 relaxation. Som...
A METHOD OF DETERMINING THE ELECTRONIC TRANSITION MOMENT FOR DIATOMIC MOLECULES
Tập 32 Số 8 - Trang 515-521 - 1954
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 transition...
