4.2 Initial orbitals.
The basis set size and structure is the same in this calculation on PrF8 and in the previous calculation on CeF8. Besides, the change experienced by the orbitals from one system to another is not dramatic. So, we can use here the same initial orbitals we used before, which have been obtained for BaF2:Ce4+ closed shell.
Copy the BaF2:Ce4+ closed shell vectors to ../vectors/$RasBlock.input.RasOrb
Use “supersymmetry” input data corresponding to those vectors.
