TL;DR
Values of the radial Schroedinger wave function or its first nonvanishing derivative at zero quark-antiquark separation are tabulated, for {ital c{bar c}], and {ital b{bar b}} levels that lie below, or just above, the flavor threshold.
Abstract
We tabulate values of the radial Schrödinger wave function or its first nonvanishing derivative at zero quark-antiquark separation, for $c\bar{c}$, $c\bar{b}$, and $b\bar{b}$ levels that lie below, or just above, flavor threshold. These quantities are essential inputs for evaluating production cross sections for quarkonium states.
