✦ Synopsis

We propose a method for deriving a set of eigenvalue equations within a subspace spanned by states which are tensor products of n Tamm-Dancoff phonons. Recursive relations allow to one solve these equations iteratively, starting from the particle-hole vacuum, and, thereby, to generate a basis of microscopic multiphonon states. The Hamiltonian has a simple spectral decomposition in such a basis and can be easily brought into diagonal form. 16 O is chosen as testing ground for the method.
