** A method and codes for two-step correlation calculation
of heavy-atom molecules have been developed, employing the generalized
relativistic effective core potential (GRECP) and relativistic coupled
cluster (RCC) methods at the** **first step, followed by nonvariational
one-center restoration of proper four-component spinors in the heavy cores.**
**Electron correlation is included for the first time in an ab initio
calculation of the interaction of the permanent**
