摘要：

We use semiclassical methods to discuss the scaling behaviour of quarkonium level splittings up to M(QQ) = 200 GeV. Special emphasis is laid on the effects of asymptotic freedom which are found to be essential for M(QQ) {greater-than or approximate} 30 GeV. The bound tt system will almost look like the Υ{hooked} system except that R = ΔM (3P2 - 3P1)/ΔM(3P1 - 3P0) is larger than 0.8. In the Υ{hooked} system R will already be close to 0.8. © 1979.
