Energy-dependent corrections to spin observables in nucleon-nucleus inelastic scattering

The 0+(p-arrow-right,p-arrow-right')0- reaction has been used as an example to elucidate the importance of the energy dependence of the nucleon-nucleon (NN) interaction on nucleon-nucleus (NA) spin observables. Because of its simplicity the 0+→0- transition is specially suited for the study of energy-dependent corrections. For this transition inclusion of corrections induced by energy dependence results in large modifications in the behavior of certain spin observables. Thus we conclude for the 0+→0- transition that calculations neglecting energy-dependent corrections are not only inconsistent but can lead to qualitatively incorrect conclusions. We argue that corrections arising from the energy dependence studied will be small for stretched states. Finally, we propose a simple procedure that will allow one to study the importance of corrections arising from the energy dependence of a proposed NN interaction in a systematic way
