主 题：Scattering Length Pairing Gap Phase Shift Fermi Momentum
摘 要：Assuming some known nucleon-nucleon interactions, and using the relations between phase shift δ and nucleon-nucleon interaction potential V (r);the relation between nucleon-nucleon interaction and scattering length a;the relation between energy gap Δ, and scattering length a;an equation is obtained between energy gap Δ and Fermi momentum kF via the phase shift δ (kF). Assuming 1s0 (singlet) pairing between the nucleons, the energy gap Δ has been calculated and it is found that Δ = 3.0 MeV at Fermi momentum kF = 0.8 fm-1.
