Phase-shift analysis of low-energy elastic-scattering data

0 v 1 7 J ul 2 00 6 Phase - shift analysis of low - energy π ± p elastic - scattering data

Using electromagnetic corrections previously calculated by means of a potential model, we have made a phase-shift analysis of the πp elastic-scattering data up to a pion laboratory kinetic energy of 100 MeV. The hadronic interaction was assumed to be isospin invariant. We found that it was possible to obtain self-consistent databases by removing very few measurements. A pion-nucleon model, base...

Phase shift analysis of low energy π±p scattering data and a comparison with pionic hydrogen data

Using newly calculated electromagnetic corrections [1], [2], we have made a phase shift analysis of the experimental data on πp elastic scattering up to a pion laboratory kinetic energy of 100 MeV. The effective hadronic interaction was assumed to be isospin invariant. The output consists of six hadronic phase shifts in parametrised form: the s-, p1/2and p3/2-waves for total isospin 3/2 and 1/2...

Low - energy elastic electron scattering by acetylene

Acetylene, C2H2, is a prototypical molecule in several respects. As a readily available gas and one of the smallest and most symmetric polyatomic molecules, it is amenable to both experimental and computational study. It is the smallest member of the important family of unsaturated hydrocarbons and is isoelectronic with N2, having in common with those molecules both a bonding πu orbital and an ...
