Opis:: We put forward a finite element method for static problems of cubic quasicrystals by variation of a suitable general potential functional. As an example we study a quasicrystal column containing a penny-shaped crack. The comparison with analytical results shows that the precision and efficiency of the numerical solution are satisfactory. The procedure can be used to solve more complicated boundary value problems and can be extended towards more sophisticated methods of crack tip loading analysis.

Opis:: Based on crystal- and ligand-field theory, double-spin-orbital coupling approach was used to analyze the crystal-field energy levels and spin-Hamiltonian parameters of $Ni^{2+}$ ion at trigonal site in $CdBr_2$. The local lattice distortion (Δ R and $τ_{Ni^{2+}}$) is estimated from the crystal field parameters; the crystal field energy Hamiltonian was diagonalized in the full basis consisting of 45 wave functions of the $Ni^{2+}$ ion. Results of calculations are in good agreement with experimental data. The reasonableness of the theoretical results is discussed.

Opis:: Energy levels and oscillator strengths have been calculated for the fine-structure transitions among the levels of the $(1s^2) 2s^2 2 p^2,$ $2s2 p^3,$ $2p^4,$ $2s^2 2p3s,$ $2s^2 2p3p,$ and $2s^2 2p3d$ configurations of Ni XXIII using the graspVU and FAC program. The extensive configuration interaction and relativistic effects have been included while generating the wave functions. The results are compared with other recent theoretical estimates, and their accuracy is assessed.

Opis:: Angular distributions of very high energy photoelectrons from Xe and Kr, excited by a 50 ps, 1054 um laser, are presented. In Xe strong, narrow structures 45° off the polarization axis appear on above-threshold ionization peaks within a limited energy range centered around 9U$\text{}_{P}$, where U$\text{}_{P}$ is the intensity-dependent ponderomotive energy. Under the same conditions the effect is much weaker in krypton. These structures are discussed using a very simple classical model as well as sophisticated single active electron calculations and the Keldysh-Faisal-Reiss theory. We conclude these structures are the result of single-electron dynamics involving rescattering of a tunneling component of the continuum wave function.

Opis:: A capacitor development effort focused on capacitors used in pulsed power and power conversion applications underwent at General Atomics Electronic Systems Inc. (GA-ESI) for decades. In recent years, funding for these efforts has accelerated the rate of development progress to the point where the time it takes to decrease the size of a capacitor by half has dropped from 10 years to 4 years. This progress made in pulsed power and power conversion capacitors will be described along with the performance characteristics of today's capacitors.
