Abstract
Gamow vectors are rigourously derived for a realistic case including a n infinite number of resonant poles. This is the case of resonances pr oduced by cut-off potentials. These are three-dimensional spherically symmetric potentials which vanish outside a bounded region. We solely consider the case of particles without internal structure and work wit h l = 0.
