Experimental and theoretical triple differential cross sections (TDCS) from ammonia are presented in the low energy regime with outgoing electron energies from 20 eV down to 1.5 eV. Ionization measurements from the 3a₁, 1e₁, and 2a₁ molecular orbitals were taken in a coplanar geometry. Data from the 3a₁ and 1e₁ orbitals were also obtained in a perpendicular plane geometry. The data are compared to predictions from the distorted wave Born approximation and molecular-three-body distorted wave models. The cross sections for the 3a₁ and 1e₁ orbitals that have p-like character were found …
