We have magneto-optically trapped all three stable neon isotopes, including the rare Ne-21, and all two-isotope combinations. The atoms are prepared in the metastable P-3(2) state and manipulated via laser interaction on the P-3(2) <-> D-3(3) transition at 640.2 nm. These cold (T approximate to 1 mK) and environmentally decoupled atom samples present ideal objects for precision measurements and the investigation of interactions between cold and ultracold metastable atoms. In this work, we present accurate measurements of the isotope shift of the P-3(2) <-> D-3(3) transition and the hyperfine interaction constants of the D-3(3) state of Ne-21. The determined isotope shifts are (1625.9 +/- 0.15) MHz for Ne-20 <-> Ne-22, (855.7 +/- 1.0) MHz for Ne-20 <-> Ne-21, and (770.3 +/- 1.0) MHz for Ne-21 <-> Ne-22. The obtained magnetic dipole and electric quadrupole hyperfine interaction constants are A(D-3(3)) = (-142.4 +/- 0.2) MHz and B(D-3(3)) = (-107.7 +/- 1.1) MHz, respectively. All measurements give a reduction of uncertainty by about one order of magnitude over previous measurements.
