Resonance couplings for the resonant states ${\mathit{P}}_{33}$(1232), ${\mathit{P}}_{11}$(1440), ${\mathit{D}}_{13}$(1520), and ${\mathit{S}}_{11}$(1535) are extracted from a recent multipole analysis of pion photoproduction data. We calculate photo

An energy-dependent partial-wave analysis of pion photoproduction data through the second-resonance region (0--1 GeV laboratory kinetic energy) is presented. A set of energy-independent analyses has also been obtained starting from the energy-depende

We confirm a recent determination of the pion-nucleon coupling constant. We relate the accuracy of our result to the abundance of low-energy polarization data. Our result has been extracted from a modified dispersion relation and is compared to the K

Comprehensive analyses of nucleon-nucleon elastic-scattering data below 1100 MeV laboratory kinetic energy are presented. The data base from which an energy-dependent solution and 22 single-energy solutions are obtained consists of 7223 pp and 5474 n

Particle scattering patterns were examined for a Coulomb potential, a Yukawa potential, and a short‐range attractive well. For the Yukawa potential and short‐range well we found structures associated with classical particle resonances. A fortran
