We find the wave function can be well approximated by new basis functions and obtain an analytic formula for the mass of the lightest bound state. Its value is consistent with the precedent results.6 pages, 2 figures. Prepared for Fifth Workshop on QCD (QCD2000), Villefranche-Sur-Mer, France, 3-7 January 2000High Energy Physics - Theorytext
