Exercise: Charge Transfer on Mn3+
1. Copy the rcg, rac, ban and plo files of als6ni2x1 to
exct1 (or any other name)
2. Modify the calculation from Ni2+ to Mn3+.
3. Start by making the rcn-files for Mn 3d4 and Mn 3d5
ground states. Run TTRCN on them and replace the Ni
parameters in the rcg-file with the Mn parameters.
4. Run TTRCG, TTRAC and TTBAN on the Mn files.
5. Plot the result
6. Modify exct1.ban in order to calculate
1. The pure 3d4 ground state
2. The pure 3d5 ground state
3. The spectrum of LaMnO3
