“…The pp and n n elastic-scattering amplitudes are both pure I = 1, whereas np and pn elastic-scattering amplitudes have an equal mixture of I = 1 and 0. The five I = 0 and five I = 1 amplitudes [I] can be related to various spin asymmetries measured with polarized beams, polarized targets, and/or polarimeters to measure the outgoing nucleon spin [2,3]. The amplitudes can also be parametrized in terms of phase-shift and elasticity parameters [4].…”

Results are presented for the spin-spin correlation parameters C,y,y and C,, for free np elastic scattering at neutron beam kinetic energies of 484, 634, 720, and 788 MeV and c.m. angles between 25" and 80". The measurements were performed with a polarized neutron beam and a polarized proton target. These are the first measurements of this type to be reported in the forward angular region with a free polarized neutron beam. The observables Css and CLs are both small at all energies, except for CLs at 788 MeV, which is larger than phase-shift analysis predictions by more than one standard deviation for most of the measured points.

“…Later, the direct reconstruction was carried out for PSI and LAMPF data and four solutions were found [6]. The direct reconstruction of the ANL-ZGS data at 6 GeV/c at six four momentum transfer -t from 0.27 to 1.0 (GeV/c)2 is described in reference [7].…”

Direct reconstruction of pp elastic scattering amplitudes from experimental data between 0.83 and 2.7 GeV

2014 La reconstruction directe des amplitudes de diffusion pp élastique est effectuée à partir des données expérimentales entre 0,83 et 2,7 GeV. La reconstruction utilise des ensembles complets d'observables dépendant du spin, mesurés lors du programme expérimental nucléonnucléon auprès de Saturne II. Les amplitudes invariantes a, b, c, d et e ont été déduites par un lissage des données expérimentales utilisant la méthode des moindres carrés. Une recherche de solutions à partir de valeurs initiales aléatoires a été effectuée pour déterminer différents ensembles possibles d'amplitudes. Les valeurs absolues des amplitudes ont le même comportement à toutes les énergies et pour toutes les solutions. Les phases présentent des ambiguités discrètes en particulier aux plus hautes énergies. Une des solutions à 2,1 GeV serait compatible avec l'existence d'une résonance dibaryonique ayant une masse proche de 2,73 GeV et une demilargeur à mi-hauteur inférieure à 50 MeV.
