Abstract
In this paper we show how the nonlinearity term affects the tunnel effect and the survival amplitude in the nonlinear Win- ter’s model. In particular, in the case of attractive nonlinearity large enough it turns out that the tunnel effect is going to disappear. Furthermore, the difficulty in giving a rigorous and appropriate definition of quantum resonances by means of the notions already used for linear equations is also highlighted.
