✦ Synopsis
A methbd for the construction of ;h& hermitaan'tiodel hakiltonian in &a framework of the quasidegenerate Rayleigh-SchCdinpr @ertuxbation theory is kuggesterj. The approach of a model hamiltonian is bati on the assunption that ifit is ~kqmE.=d in a chosen fmitedimension~ model space it will yield eigenvalues of the origin&l hzmiltonian in the entire H&ert space, For a unitary operator tra'nsforming ihe unperturbti~stite vectors onto the prturbed rtite vectors, md P model-interaction operator, the pcrh\rbo~oncxp3nsionformSe are developed.
