Spline-interpolation solution of 3D Dirichlet problem for a certain class of solids
No full textWe present a spline-interpolation approximate solution of the Dirichlet problem for the Laplace equation in axisymmetric solids, cones and cylinders. Our method is based on reduction of the 3D problem to a sequence of 2D Dirichlet problems. The main advantage of the spline-interpolation solution of the 3D Dirichlet problem is its continuity in the whole domain up to the boundary even for the case of linear spline. © 2012 The Author 2012.

Coherent production of the 3 system on nuclei II. Target dependence of the \1^{+}S phase variation
No full textElectron spin resonance of Eu 2 + in the Eu doped clathrate Ba 6Ge 25
No full textWe report electron spin resonance (ESR) investigations of the clathrate compound Ba 6-x Eu xGe 25 (x=0.03–0.4) which exhibits a temperature induced, two-step reconstructive structure transformation at temperatures between 185 K and 223 K. The linewidth of the Eu 2+ ESR proves to be sensitive to the transformation. Another anomaly in the temperature dependence of the linewidth is found near T=60 K which points towards another possible structural transition. Both anomalies seen in the ESR linewidth are not sensitive to the Eu content in contrast to the strong Eu-concentration dependence of transport properties.

The total cross-section of (5pi)-nucleon collision
No full textCoherent 5π production on nine nuclear targets has been studied at 40 GeV incident energy at the Serpukhov accelerator (CERN-Serpukhov experiment No. 5). The collision cross section of the 5π system on the nucleon has been determined in the frame of the Kölbig-Margolis-Glauber model; its value, <10 mb, is definitely lower than the (3π)-nucleon cross section at the same energy
Evidence for new resonances in the systems
No full textPartial-wave analysis has been performed on 120 000 - -+ events coherently produced on nuclear targets in a - beam of 40 GeV/c. Evidence has been found for a 0- S resonance at 1.24 GeV with a width 0.36 GeV. The data also suggest the presence of another 0- S resonance of similar width near 1.8 GeV. These observations can be interpreted as radial excitations of the meson
Coherent production of 3pi states at 25 GeV/c
No full textThe coherent production of π-π-π+ states has been studied at 25.7 GeV incident energy with an Al target. The partial-wave analysis of the data confirms the evidence of a I GJPL=1-0- S resonant state in the mass region near to 1.2 GeV, already found by our collaboration at 40 GeV incident energy
