The motivation for this is to supply the necessary theoretical tools to calculate scattering observables of these many-body systems. Concepts which are seemingly different for atomic/molecular scattering from those of nuclear systems, are shown to be the same once physical units such as energy and length are diligently clarified. Many-body resonances excited in nuclear systems are the same as those in atomic systems and come under the nameQuantum scatteringScattering (Physics)Quantum scattering.Scattering (Physics)539.7/58539.758Canto Luiz Felipe1633894Hussein M.
