We present a multichannel-scattering calculation of elastic and inelastic cold collisions between two low-field seeking, metastable 88Sr [(5s5p)3P2] atoms in the presence of an external magnetic field. The scattering physics is governed by strong anisotropic long-range interactions, which lead to pronounced coupling among the partial waves of relative motion. As a result, nonadiabatic transitio...

Magnetic Raman scattering from a frustrated spin–1/2 Heisenberg–chain is considered with a focus on the uniform phase of the spin–Peierls compound CuGeO3. The Raman intensity is analyzed in terms of a Loudon–Fleury scattering process using a spinless–fermion mean–field theory developed for the frustrated spin–chain. A comparison to experimental data is presented and the frustration and temperat...

High precision photoelectron energy and angular distributions in helium and neon atoms for a broad intensity range reflect the change in the continuum dynamics that occurs as the ionization process evolves into the pure tunneling regime. Elastic rescattering of the laser-driven free electron from its parent ion core leaves a distinct signature on the spectra, providing a direct quantitative tes...

The paper discusses the fast seismic performance assessment of structures using truncated pulse-like ground motion records. It is shown that it possible to truncate a signal novel wavelet-based definition identifies duration predominant velocity pulse. time-history still able efficiently reproduce increased demand near-field records typically produce. Substituting original with signal, can sign...

In this study, the effective parameters on the inelastic response of asymmetric buildings is evaluated for an ensemble of real Iranian earthquake records by considering soil-structure interaction. Then, the design eccentricity obtained from the inelastic dynamic soil-structure analysis is compared with the design eccentricity of seisimic codes of Iran, ATC-3, New Zeland, Canada, Mexico, Austral...

We have measured inelastic electron-deuteron, electron-proton, and electron-aluminum cross sections at 10' in the kinematic region between-elastic deuteron scattering and the second resonance region at six beam energies between 9.8 and 21 GeV. The elastic electron-neutron cross section was extracted from the quasi-elastic data at Q2 = 2.5, 4.0, 6.0, 8.0 and 10.0 (GeV/c)'. The ratio of elastic c...
