Using previously derived expressions for axial gauge propagators and vertex functions in the infrared limit of pure Yang-Mills theory, we show that at long-range quantum Yang-Mills theory is equivalent to a classical Yang-Mills theory in an anisotropic and inhomogeneous medium, the QCD vacuum. The properties of this classical theory are described and possible applications are outlined.

The level structure of 13N has been studied by the elastic scattering of polarized protons from carbon. Angular distributions of the analyzing power and differential cross section have been measured at 40 proton lab energies between 11.5 and 18 MeV. A phase-shift analysis of the data produced level parameters for the following T = 12 states in 13N with Jπ(E2); 32+ (14.06 MeV), 72+ (16.00 MeV), 32+ (18.16 MeV) and12− (18.18 MeV).
