In the framework of the random phase approximation in the continuum we calculate the strength function of the [Formula Presented] isoscalar monopole giant resonance in [Formula Presented]. The one-particle continuum plays an important role in the formation of the structure of the strength function. Most interesting is the appearance of some narrow resonances at large excitation energy. We discuss the results obtained from the point of view of resonance trapping which is known to appear due to the strong coupling of the resonance states via the continuum. © 1999 The American Physical Society.
