Angle-dependent normalization of neutron-proton differential cross sections
J. J. de Swart, R. G. E. Timmermans
Systematic errors in the database of differential cross sections below 350 MeV are studied. By applying angle-dependent normalizations with the help of the energy-dependent Ni…
Normalization of neutron-proton differential cross sections
M. C. M. Rentmeester, R. G. E. Timmermans, J. J. de Swart
The np differential cross section below 350 MeV neutron laboratory energy is studied using the energy-dependent Nijmegen partial-wave analysis PWA93. We analyze in detail three exp…
Chiral two-pion exchange and proton-proton partial-wave analysis
M. C. M. Rentmeester, R. G. E. Timmermans, J. L. Friar +1
The chiral two-pion exchange component of the long-range pp interaction is studied in an energy-dependent partial-wave analysis. We demonstrate its presence and importance, and det…
Comment on piNN Coupling from High Precision np Charge Exchange at 162 MeV
M. C. M. Rentmeester, R. A. M. Klomp, J. J. de Swart
In this updated and expanded version of our delayed Comment we show that the np backward cross section, as presented by the Uppsala group, is seriously flawed (more than 25 sd.). T…
The Status of the Pion-Nucleon Coupling Constant
J. J. de Swart, M. C. M. Rentmeester, R. G. E. Timmermans
A review is given of the various determinations of the different piNN coupling constants in analyses of the low-energy pp, np, pbarp, and pi-p scattering data. The most accurate de…
Electromagnetic Corrections to the One-Pion-Exchange Potential
U. van Kolck, M. C. M. Rentmeester, J. L. Friar +2
Leading-order electromagnetic loop corrections to the one-pion-exchange potential are computed within the framework of chiral perturbation theory. These corrections generate an eff…
