Abstract
A nonrelativistic Hamiltonian with plausible spin dependent corrections is
proposed for the quarkonia below their respective strong decay thresholds. With
only six free parameters this model reproduces the nine known masses of the
bottomonia within about 1 MeV, the six known masses of the charmonia within a
few MeV and the five known leptonic decay widths of the 3S1 states within
about 20 %. The model is then used to predict the masses of the
remaining 43 quarkonia (some of them for the first time) and of the leptonic
decay widths of the two states. Comparison with some
other models is made.
