Resumen:
We extend the standard Friedrichs model with an extra term that includes time-dependent interactions. Thetime dependence of the poles of the reduced resolvent of the model is explicitly calculated. It is found that thesepoles behave as analytical functions of the added time-dependent interaction. The present results are comparedwith the ones reported by K¨albermann, concerning the assisted tunnelling of α particles.
