Abstract
A variational calculation scheme is proposed to tackle the non-unitarity problem in the
Dyson boson description of nuclear collective motion. It is based on a trial-state-optimization
variational prkciple in which one minimizes the deviation of a trial state from being an exact
eigenstate, instead of minimizing the energy expectation value in the trial state as is usually
done in standard variational calculations. The viability of this variational method is demonstrated
through an application to a monopole pairing interaction for multi-j shells.
