Dear Hyungjun,

in this work we actually used symmetry equivalenced HF orbitals, so the input for that part is a bit more complicated than your (symmetry-broken) case below.  I've attached a somewhat simplified version of the exact input used for the paper/calculations referenced below.

best regards,

Dear Molpro users,

I am trying to reproduce the ionization potential of Hf atom ( J. Chem. Phys, 130, 164108, 2009)

When I did the CCSD(T)/cc-pVTZ-PP calculation, the IP value is slightly different from the reported value.

My calculation gives 150.20 kcal/mol but the reported value is 149.93 kcal/mol.

I think I missed something in the input file.

I have attached my input file here, Any comments are welcome.
