Abstract
We derive the 2 Delta(0)/T-c ratio in a d-wave superconductor with the norm
al state described by a non-Fermi liquid model, where the Green's function
is assumed to have the Anderson-Balatsky form G(0)(k,omega) = w(c)(-alpha)/
(i omega - epsilon(k))(1-alpha). We showed how a nonzero value for alpha in
fluences the value of the ratio 2 Delta(0)/T-c. (C) 1999 Elsevier Science B
