The Resonances of n, ec, a - System at Astrophysical Energy Region

摘要

The series of narrow resonances in n, a, a scattering amplitude at very low energies has been found. The lifetimes of these three body resonances are close to the lifetime of unstable nucleus 8Be, Consideration of three body scattering has been carried out on base of well-known Faddeev's equations with simple separ able forms of two body repulsive potentials. The three body effective potential has been obtained in analytical form in this case. The physical model and explanation of the resonance phenomena in systems consisted of one neutron and two or more a-particles is given to prove appearance of the resonance set. The existence of narrow resonances can stimulate a few-body fusion in systems that give result in many astrophysical phenomena.
