    Total cross section measurements for positron scattering from acetone

    We report results from total cross section measurements for positron-acetone scattering. The energy range of these experiments was 0.2-23 eV, while the energy resolution of our positron beam was ~260 meV. The ...

    Near-threshold electron-impact excitation of argon studied with the time-of-flight technique

    Absolute angle-differential cross-section data are presented for excitation of the 3p54s manifold in argon by electron impact. The investigation focuses on the near-threshold region, where previous studies have r...

    Upper critical field Hc2 in Bechgaard salts (TMTSF)2PF6

    The symmetry of the superconductivity in Bechgaard salts is still unknown, though the triplet pairing has been established by Hc2 and NMR for (TMTSF)2PF6. The large upper critical field at T = 0K (Hc2 ~ 5 Tesla) ...

    Evolution of structure of SiO2nanoparticles upon cooling from the melt

    Evolution of structure of spherical SiO2 nanoparticles upon cooling from the melt has been investigated via molecular-dynamics (MD) simulations under non-periodic boundary conditions (NPBC). We use the pair inter...

    Ab-initiocalculations of spin tunneling through an indirect barrier

    We use a fully relativistic layer Green's functions approach to investigate spin-dependent tunneling through a symmetric indirect band gap barrier like GaAs/AlAs/GaAs heterostructure along [100] direction. The...
