ABSTRACT

The present work is devoted to study of spectroscopic aspects, in terms of neutron strength function, for the threshold effects with non-light nuclei. Relations to the neutron strength functions of the anomal effects observed at threshold of neutron analogue channel, in deuteron stripping reactions on A ≈ 90 mass target nuclei and in nucleon mirror reactions with A ≈ 30 nuclei, are established. It is proved that these threshold effects follow the mass dependance of the neutron strength functions.The connection between threshold effects and neutron strength functions, proves that the threshold effects are related to spectroscopy of ancestral zero-energy neutron particle resonance. One can conclude the threshold effects depend not only on penetration factors of opening neutron channel, as in Cusp Theory, but also on Multichannel Reaction Dynamics as well as on Spectroscopy of neutron threshold state.The present study is based on Reduced Scattering Matrix, describing the effect of invisible threshold channel on open observed ones. The determining role of Nuclear Reaction Dynamics, Quasiresonant Scattering and Spectroscopy of Neutron Threshold State, on threshold effects is evinced. More... »
