Higher-order multipole amplitudes in charmonium radiative transitions
Using 24 million ψ′ ≡ ψ(2S) decays in CLEO-c, we have searched for higher multipole admixtures in electric-dipole-dominated radiative transitions in charmonia. We find good agreement between our data and theoretical predictions for magnetic quadrupole (M2) amplitudes in the transitions ψ′ → γχc1,c2 and χc1,c2 → γJ/ψ, in striking contrast to some previous measurements. Let b2 and a2 denote the n...
متن کاملTests of Planar Permanent Magnet Multipole Focusing Elements*
In recent work, planar configurations of permanent magnets were proposed as substitutes for conventional current-driven iron quadruples in applications limited by small apefiure sizes and featuring small beam occupation diameters. Important examples include the configuring of focusing lattices in -.. small-gap insetiion devices, and the implementation of compact mini-beta sections on linear or ...
متن کاملMultipole solitary wave solutions of the higher-order nonlinear Schrödinger equation with quintic non-Kerr terms
We consider a high-order nonlinear Schrödinger (HNLS) equation with thirdand fourth-order dispersions, quintic non-Kerr terms, self steepening, and self-frequency-shift effects. The model applies to the description of ultrashort optical pulse propagation in highly nonlinear media. We propose a complex envelope function ansatz composed of single bright, single dark and the product of bright and ...
متن کاملCommunication: Accurate higher-order van der Waals coefficients between molecules from a model dynamic multipole polarizability.
Due to the absence of the long-range van der Waals (vdW) interaction, conventional density functional theory (DFT) often fails in the description of molecular complexes and solids. In recent years, considerable progress has been made in the development of the vdW correction. However, the vdW correction based on the leading-order coefficient C6 alone can only achieve limited accuracy, while accu...
متن کاملA Fast Multipole Method for Higher Order Vortex Panels in Two Dimensions
Higher order panel methods are used to solve the Laplace equation in the presence of complex geometries. These methods are useful when globally accurate velocity or potential fields are desired as in the case of vortex based fluid flow solvers. This paper develops a fast multipole algorithm to compute velocity fields due to higher order, two-dimensional vortex panels. The technique is applied t...
