Abstract
A brief outline of the Lorentz integral transform (LIT) method is given. The method is well established and allows treatment of reactions into the many-body continuum with bound-state-like techniques. The energy resolution that can be achieved is studied by means of a simple two-body reaction. From the discussion it will become clear that the LIT method is an approach with a controlled resolution and that there is no principle problem to even resolve narrow resonances in the many-body continuum. As an example, the isoscalar monopole resonance of is considered. The importance of the choice of a proper basis for the expansion of the LIT states is pointed out. By employing such a basis, a width of 180(70) keV is found for the isoscalar monopole resonance when using a simple central nucleon-nucleon potential model.
