Variational approach to resonant states of many-particle systems

A variational approch is proposed for the approximate description of decaying states represented by Gamow functions. The method is suited to describing many-particle systems with antisymmetry.

Summary:A variational approch is proposed for the approximate description of decaying states represented by Gamow functions. The method is suited to describing many-particle systems with antisymmetry. It is shown that, in combination with a generator-coordinate basis, its actual application is as feasible as an ordinary bound-state generator-coordinate calculation. Model calculations reveal that, as an approximation method, it has very favourable properties.
