Neutron inelastic scattering from 40Ca at 21.7 and 25.5 MeV

Differential cross sections for the scattering of neutrons from ⁴⁰Ca for states up to 5 MeV excitation energy have been measured at 21.7 and 25.5 MeV. The analysis is done using a coupled channel formalism in terms of a vibration collective model. The results using a usual standard Woods-Saxon form factor for the transitions are compared with those obtained using form factors derived from a model-independent analysis to the elastic cross sections.
