Canto Física, Astronomía y Matemáticas Nuclear fusion Nuclear reaction We investigate the effect of Pauli non-locality in the heavy-ion optical potential on sub-barrier fusion reactions.The Sao Paulo potential, which takes into account the Pauli non-locality and has been widely used inanalyzing elastic scattering, has also recently been applied to heavy-ion fusion. However, the approximationemployed in deriving the Sao Paulo potential, based on the Perey-Buck semi-classical treatment of neutron inducedreactions, must be assessed for charged particles tunneling through a barrier. It is the purpose of this noteto look into this question. We consider the widely studied system 16O + 208Pb at energies that span the barrierregion from 10 MeV below to 10 MeV above. It seems that the non-locality plays a minor role. We find the SaoPaulo potential to be quite adequate throughout the region. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437718 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.37 |
