We implemented the state-specific Brillouin-Wigner coupled-cluster method for the complete model space spawned by four reference configurations generated by two electrons in two active orbitals. We applied the method (together with previously suggested a posteriori size-extensivity correction) to the calculation of spectroscopic constants of the Ibr molecule, using a relativistic effective core potential.
