CORRELATIONS AMONG OBSERVABLES IN TWO- AND THREE-NUCLEON SYSTEMS.

We study the elastic nucleon-deuteron scattering process at incomingnucleon laboratory energies up to E = 200 MeV working within the formalism of Faddeev equations. We focused here on the computation and systematic analysis of the correlation coefficients among various observables in nucleon-nucleon and nucleon-deuteron elastic scattering. As a result, we obtained pairs of correlated/uncorrelated observables or sets of very weakly correlated observables. The knowledge, if some observables are or are not correlated, would impact future methods of fixing free parameters of the two- and many-body potentials, and could possibly help determine observables which should be measured to increase the precision of potential parameters' determination.
