The Fano effect has been known as the quantum interference effect caused by the correlation between continuum and a sharp resonance or bound state [1]. In quantum physics, there are many examples of the Fano effect such as Raman scattering [2,3], photoelectric emission [4], photoionization [5] etc. Very recently, we have succeeded to derive the Fano resonance parameters for the neutron elastic scattering off the open-shell nucleus with the help of the HFB Jost function formalism [6,7]. This is the first derivation of the Fano parameters as the effect of the pairing correlation in quantum physics. We will introduce the derivation of the Fano parameters and the results of analysis at the conference. References [1] U. Fano, Phys. Rev. 124, 1866 (1961). [2] F. Cerdeira, T. A. Fjeldly, and M.
