Résumé
Nous avons mesuré le pouvoir d'analyse neutron-proton Ay(θ) à 7.6, 12.0, 14.1, 16.0 et 18.5 MeV. Cette observable s'avère importante pour déterminer les déphasages 3P0, 1, 2 de la diffusion n-p. Nous comparons les données aux prédictions de 2 analyses en déphasages (dont l'une incorpore les effects BIC) et aux prédictions faites avec les potentiels de Paris et de Bonn.
Abstract
Neutron-Proton Ay(θ) measurements have been made at 7.6, 12.0, 14.1, 16.0, and 18.5 MeV. A sensitivity study establishes the importance of Ay(θ) in determining the 3P0, 1, 2 phase shifts in n-p scattering. The data are compared to the predictions of two phase-shift studies (one of which incorporates CIB effects), and the Paris and Bonn NN potenials.
