Opis:
The spin resonance of excess electrons is observed with the detection either on the neutral or the negatively charged exciton X$\text{}^{-}$ emission in type I CdTe/(Cd,Mg)Te quantum wells with excess electrons of low density. It is found that the electron spin-dependent and electron spin-conserving formation and recombination of X$\text{}^{-}$ make the optical detection of the spin resonance of excess electrons feasible. For the first time, optically detected magnetic resonance is used to study fast optical transition processes in the nanosecond timescale where the microwave-induced magnetic transition rate is much lower than the optical transition rate.

Opis:
Relativistic configuration interaction calculations with the inclusion of the Breit interaction, quantum electrodynamics and finite nuclear mass corrections have been carried out in the extended optimal level scheme using multi-configuration Dirac-Fock wave functions on the wavelengths, electric dipole transition rates and oscillator strengths of chlorine. Through the use of the active space method, the calculated values are compared with the other available data on He-like and Be-like chlorine and are found to be in very good agreement with them. In this paper we give accurate transition properties from Cl(VIII) through Cl(XVI). These data provide reference value for level lifetime, charge state distribution and average charge of chlorine plasma.

Opis:
In the paper density functional theory method was applied to explore the electronic and magnetic properties of the GdNiSb in low-temperature phase with cubic MgAsAg-type structure and in the high-temperature phase. The calculations were performed by first principles full-relativistic full potential local orbital method within the local spin density approximation. The calculations results show the metallic character of GdNiSb compound in the high-temperature phase with hexagonal $AlB_2$-type structure. For the low-temperature phase of the cubic GdNiSb system, they indicate a semiconducting behavior. The density of states below the Fermi level is greater in high-temperature phase than in low-temperature one, the calculated magnetic moment is in good agreement with an available experimental value.

Opis:
Molecular dynamics simulations with condensed-phase optimized molecular potentials for atomistic simulation studies force field are performed to investigate the structure, equation of state, and mechanical properties of high energetic material pentaerythritol tetranitrate. The equilibrium structural parameters, pressure-volume relationship and elastic constants at ambient conditions agree excellently with experiments. In addition, fitting the pressure-volume data to the Birch-Murnaghan or Murnaghan equation of state, the bulk modulus B₀ and its first pressure derivative B'₀ are obtained. Moreover, the elastic constants are calculated in the pressure range of 0-10 GPa at room temperature and in the temperature range of 200-400 K at the standard pressure, respectively. By the Voigt-Reuss-Hill approximation, the mechanical properties such as bulk modulus B, shear modulus G, and the Young modulus E are also obtained successfully. The predicted physical properties under temperature and pressure can provide powerful guidelines for the engineering application and further experimental investigations.

Opis:
Novel nanometer scale structures have been produced by thermal heating or laser irradiation on the surface of single- and multi-layers of C$\text{}_{60}$ and C$\text{}_{84}$ on Si. These structures were examined by combined measurements of scanning tunneling spectroscopy and high resolution electron energy loss spectroscopy. The results show specific chemical reactions of substrate with carbon clusters having single- and double-bonded network. Covalent bonds are formed in some of these chemical reactions.
