Abstract

This contribution reports, to the best of our knowledge, for the first time on the neutron tunneling phenomenon in nickel isotopes based nanostructured. More accurately, 58Ni-62Ni-58Ni thin films Fabry-Perot resonator configuration exhibited several tunneling resonances. In total, there were 7 tunneling resonances. These tunneling resonances manifest themselves via sharp dips in the total reflection plateau due to quasi-bound states in the nanostructured isotopic based nickel thin film Fabry-Perot resonator.
