The search for non-Abelian quantum Hall states in the second Landau level is narrowed to the range of filling factors 7/3 < nu(e) 8/3. In this range, the analysis of energy spectra and correlation functions, calculated including finite width and Landau-level mixing, supports the prominent non-Abelian candidates at nu(e) = 5/2 (Moore-Read) and 12/5 (Read-Rezayi). Outside of it, the four-flux noninteracting composite fermion model is validated. The borderline nu(e) = 7/3 state is adiabatically connected to the Laughlin liquid, but its short-range correlations and charge excitations are different.
