Neutron-deuteron analyzing power data at 19.0 MeV

Measurements of neutron-deuteron (n-d) analyzing power Ay(θ ) at En = 19.0 MeV are reported at 16 angles from θc.m. = 46.7 to 152.0◦. The objective of the experiment is to better characterize the discrepancies betweenn-d data and the predictions of three-nucleon calculations for neutron energies above 16.0 MeV. The experiment used a shielded neutron source, which produced polarized neutrons via...

1 Analyzing power of the ~ pp → ppπ 0 reaction at beam energy of 390 MeV

The analyzing power of pp → ppπ 0 reaction has been measured at the beam energy of 390 MeV. The missing mass technique of final protons has been applied to identify the π 0 production event. The dependences of the analyzing power on the pion emission-angle and the relative momentum of the protons have been obtained. The angular dependence could be decomposed by the Legendre polynomial and the r...

Precise set of tensor analyzing power T20 data for the deuteron-proton breakup at 130 MeV

High-precision tensor analyzing power T20 data of the H(d,pp)n reaction at 130MeV beam energy have been determined for 81 kinematical configurations. They are compared to theoretical predictions based on various approaches to describe the dynamics of the three-nucleon (3N) system. The calculations are performed using modern realistic nucleon-nucleon potentials combined with three-nucleon force ...
