Abstract: | We use semiclassical methods to discuss the scaling behaviour of quarkonium level splittings up to . Special emphasis is laid on the effects of asymptotic freedom which are found to be essential for . The bound t system will almost look like the ? system except that is larger than 0.8. In the ? system R will already be close to 0.8. |
