On-shell T-matrices in multiple scattering
The transition operator T for the scattering of a particle from N potentials Vj(x) can be expanded into a series featuring the transition operators tj associated with the individual potentials. For Vj(x) both absolutely and square integrable in x, we show, using an analytic continuation argument, that if T is on-shell, i.e. in < k|T (σ2 ± i0)|k′ >, |k| = |k′| = σ, then each tj is also on-shell....
متن کاملScattering Properties of Core–Shell Particles in Plastic Matrices
Blending submicron rubber particles with plastics can enhance the mechanical strength of the composite material. However, the difference in refractive index between the particle and matrix scatters light, making the material more opaque. We consider the possibility of reducing a particle’s scattering cross section by adding coatings. We find that adding coatings can reduce the amount of scatter...
متن کاملOff-Shell Structures of Nucleon-Nucleon t-matrices and their Influence on Nucleon-Nucleus Elastic Scattering Observables
The sensitivity of nucleon-nucleus elastic scattering observables to the offshell structure of nucleon-nucleon t-matrices, derived from realistic NN potentials, is investigated within the context of a full-folding model based on the impulse approximation. Our study uses recently developed NN potential models, which describe a subset of the NN data base with a χ2 per datum ∼1, which means that t...
متن کاملInduced on-shell supersymmetry in eikonal scattering.
Generically coupled neutral scalar bosons and chiral fermions are shown, in the eikonal kinematical limit, to be described by a reduced (free field) theory with N = 1 on-shell supersymmetry. Charged scalars and spinors turn out to be described in the eikonal limit by a reduced interacting theory with a modified and restricted on-shell N = 1 supersymmetry. Consequences of such a symmetry for the...
متن کاملCentric connectivity index by shell matrices
Relative centricity RC values of vertices/atoms are calculated within the Distance Detour and Cluj-Distance criteria on their corresponding Shell transforms. The vertex RC distribution in a molecular graph gives atom equivalence classes, useful in interpretation of NMR spectra. Timed by vertex valences, RC provides a new index, called Centric Connectivity CC, which can be useful in the topologi...
