1: Relativistic multichannel theory can calculate the physical parameter
($\mu_{\alpha}$,$U_{i\alpha}$) in MQDT for any atoms in both negative and
positive energy ranges. 2: The calculated fine structure of nf Rydberg
states for alkali atoms are in good agreement with measured values.
3: The atomic structures of high-Z atom Pb are also studied.
