Abstract
One of the tools to study spin structure of short range correlations (SRCs) and three nucleon forces is the measurement of the polarization observables. Deuteron induced reactions at intermediate energies are investigated at Internal Target Station (ITS) of Nuclotron through the dp elastic and dp → ppn reactions. Analyzing powers iT11 and T20 analyzing powers of dp → ppn reaction at 400 MeV are presented.
Highlights
Reactions with few nucleons have a rich phase space
Reactions dp elastic and dp → ppn are studied in intermediate energy region from 300 - 2000 MeV and 300 - 500 MeV with unpolarized and polarized beam at Nuclotron with the aim of the study of a few nucleon correlations
Values of the vector analyzing powers iT11 at 72.3° and 76.5° in centre of mass system (CMS) are 0.10 ± 0.02 and 0.11 ± 0.06, respectively
Summary
Reactions with few nucleons have a rich phase space. Polarization observables can be measured under various kinematic conditions. The most used contribution in theoretical models which include three nucleon forces (3NFs) is two pion exchange, e.g. Urbana IX [1] and Tucson-Melbourne [2]. These models properly describe binding energies of three and four nucleon systems. The investigation of dp → ppn reaction at deuteron energy of 270 MeV at RIKEN [7] and IUCF [8] reveals that vector analyzing power Ay can be described using only NN forces. Reactions dp elastic and dp → ppn are studied in intermediate energy region from 300 - 2000 MeV and 300 - 500 MeV with unpolarized and polarized beam at Nuclotron with the aim of the study of a few nucleon correlations
