Interatomic potential and phonon spectrum of potassium in the framework of the multiple scattering method
Springer Science and Business Media LLC - Tập 34 - Trang 293-295 - 1991
A method of calculating the interatomic potential based on electron density functional formalism and multiple scattering theory is considered. The interatomic pair potential, vacancy formation energy, elastic shear moduli, and phonon spectrum were computed within the framework of this procedure. Satisfactory agreement of the calculated results with experiment was obtained.

Thời gian tồn tại của trạng thái kích thích của các phân tử phức tạp trong pha khí dưới kích thích anti-Stokes Dịch bởi AI
Springer Science and Business Media LLC - Tập 16 - Trang 462-465 - 1973
Sự phụ thuộc của thời gian trung bình của phát xạ huỳnh quang (Τ) của các hơi phân tử phức tạp loãng được điều tra bằng phương pháp huỳnh quang theo quang phổ hấp thụ dưới sự kích thích anti-Stokes. Một số dẫn xuất phthalimide được sử dụng làm đối tượng nghiên cứu. Đã xác định rằng thời gian trung bình của phát xạ huỳnh quang đối với các hợp chất đã nghiên cứu vẫn giữ nguyên trong toàn bộ khoảng k...... hiện toàn bộ

Hot-carrier magnetophonon resonance in CdxHg1−xTe
Springer Science and Business Media LLC - Tập 37 - Trang 1140-1142 - 1994
Resistance oscillations and voltage-current characteristics have been examined for CdxHg1−xTe crystals on both sides of the transition from the gap-free phase to the narrow-gap phase in strong electric fields (1... hiện toàn bộ
Double focusing method for the coherent tomography of inhomogeneous media
Springer Science and Business Media LLC - Tập 40 - Trang 391-395 - 1997
A new method of double focusing is proposed for the tomography of inhomogeneous media which combines the approaches of active and passive coherent probing schemes. In combination with spatial filtering, this makes it possible to resolve inhomogeneities as small as half the operating wavelength in the probed medium. The satisfactory operation of the method is confirmed by the results of simulation ...... hiện toàn bộ
Local order in the Ni-Ta system
Springer Science and Business Media LLC - Tập 19 - Trang 1543-1546 - 1976
Short-range order in the Ni -Ta system is studied both experimentally (by diffuse scattering of x rays) and theoretically (by the pseudopotential method). The existence of local order is found in the alloy Ni-7 at. % Ta. The short-range order parameter calculated by the pseudopotential method, using Animalu form factors, coincided in sign with that observed experimentally.
Interatomic-bonding energetics and stability characteristics for NaBr-KBr and NaCl-KCl solid solutions
Springer Science and Business Media LLC - Tập 15 - Trang 1765-1769 - 1972
Based on experimental data on elasticity constants and elastic moduli, several energy and stability characteristics are calculated for NaBr-KBr and NaCl-KCl solid solutions.
Dependence of average multiplicity on impact parameter and momentum transfer
Springer Science and Business Media LLC - Tập 22 - Trang 236-240 - 1979
Using a previously proposed model as a basis, an investigation is made of the functional dependence of the average multiplicity on impact parameter and momentum transfer. The results are compared with those obtained using a probabilistic approach. The advantage of this method is that the information desired is derived from elastic scattering data.
