I understand that nuclei can overcome some of their binding energy by being excited, which allows them to promptly emit nucleons. Is there any requirement as to how this energy is delivered/ obtained? For example, a Be 9 nucleus emits a neutron when excited via photon to 1.667 MeV. Would the same emission occur if a Be 9 4+ ion (Be 9 nucleus) were accelerated to 1.667MeV of kinetic energy? In short, are these types of reactions effected by how the nucleus gains the energy needed to trigger them?
