Abstract

Detailed measurements of vector and tensor analyzing powers of the ^{2}{\rm H}(\vec d,dp){n} break-up process are presented. The data were obtained using a polarized deuteron-beam with an energy of 65 MeV/nucleon impinging on a liquid-deuterium target. The experiment was conducted at the AGOR facility at KVI using the BINA 4\piπ-detection system. The focus of this contribution is to analyze data of the dddd scattering process in the regime at which the neutron acts as a spectator, which we refer to as the quasi-free (QF) limit. To achieve this, events for which the final-state deuteron and proton are coplanar have been analyzed and the data have been sorted for various reconstructed momenta of the missing neutron. In the limit of vanishing neutron momentum and at small deuteron-proton momentum transfer, the data match very well with measured and predicted spin observables of the elastic deuteron-proton scattering process. The agreement deteriorates rapidly with increasing neutron momentum and deuteron-proton momentum transfer. The results of coplanar configurations in four-body phase space are compared with the results of recent available theoretical calculations based on the Single-Scattering Approximation.

Highlights

  • Development of boson-exchange models [1] led to several phenomenological nucleon-nucleon (NN) potentials which have successfully described the interaction between two nucleons with χ2 ∼ 1

  • Recent theoretical calculations are available that are based on the singlescattering approximation (SSA)

  • We present the results of an investigation of the 2H(d, d p)n break-up process for coplanar configurations including Quasi-Free (QF) region at deuteron-beam energy of 65 MeV/nucleon

Summary

Introduction

Development of boson-exchange models [1] led to several phenomenological nucleon-nucleon (NN) potentials which have successfully described the interaction between two nucleons with χ2 ∼ 1. These calculations are expected to be valid in the quasi-free (QF) regions for beam energies larger than 100 MeV [29, 30]. We present the results of an investigation of the 2H(d, d p)n break-up process for coplanar configurations including Quasi-Free (QF) region at deuteron-beam energy of 65 MeV/nucleon.
