First results on –
d are reported. The measurements were made using 8 specially designed neutron counters, which were carefully calibratedin situ. The differential cross sections atT
=142, 180, 217, and 254 MeV were obtained at four angles between 0° and 90°, they are compared to +
d pp data measured at the same energies and angles with the same setup. At every beam energy, the shape of the angular distributions of –
d nn and +
d pp is the same to ±2%. The absolute cross sections differ by 1 to 10%. The error in this comparison is ±4% implying a small violation of charge symmetry.Dedicated to Prof. I. laus on the occasion of his 60th birthdayDeceased 相似文献

The computation of the interaction energy between an adsorbed dye molecule and the silver halide surface has been accomplished through the use of a new code which is based upon CHEMLAB. The surface interaction energies have been computed for 1,1′-ethylene-2,2′-cyanine, a dye molecule, in both monomeric and aggregated configurations on the (100) surfaces of AgBr and AgCl. The model predicts reasonable configurations for the adsorbed dye monomer and its H- and B-aggregates. At high dye levels, the adsorption of aggregated forms is found to be favored over an adsorbed monolayer of monomeric dye molecules. Using the current interaction potentials, however, it was found that the adsorption of the dye on the AgCl (100) surface was slightly favored over that on the AgBr (100) surface. This finding, although at variance with experimental data, may be attributed to the use of an unrelaxed silver halide surface in these computations. 相似文献

We report the preparation of N‐heterocyclic carbene (NHC)‐stabilized compounds containing P=B double bonds. The reaction of the highly functionalized phosphinoborane Mes*(SiMe3)P?B(Cl)Cp* with Lewis bases allows access to base‐stabilized phosphinidene boranes Mes*P=B(L)Cp* (L=4‐dimethylaminopyridine (DMAP), NHC) by Me3SiCl elimination. The formation of these species is shown to proceed through transient borylphosphide anions generated by Me3Si abstraction. 相似文献

A volume of fluid (VOF) method is developed combining a first‐order limited downwind scheme with higher order accurate schemes. The method is characterized by retaining a sharp fluid interface and a reduction in numerical diffusion near the interface, but avoids complicated geometrical reconstruction as occurs in most volume tracing algorithms. To demonstrate the accuracy and robustness of the method, a selection of numerical experiments are presented involving a pure advection problem, a water wave impact caused by a dam breaking and liquid sloshing in a partially filled tank.
