A beam of α particles falls on 9Be nuclei. A resonance it is observed for an incidence energy of 1.732 MeV. a) Calculate the excitation energy ∆E of the corresponding state of the composite nucleus. b) The same state of resonance occurs in the collision of neutrons with 12C nuclei, Calculate the energy of the neutron beam in this resonance condition.
