Rk. Pandey et al., A possible explanation of critical temperature and isotope effect coefficient of high T-c cuprate superconductors, J SUPERCOND, 11(6), 1998, pp. 663-665
The expressions for superconducting transition temperature (T-c) and isotop
e effect coefficient (alpha) have been derived from a generalized integral
gap equation for a strongly coupled superconductor, when electrons-phonons
and electrons-biexcitons are simultaneously present in high-T-c cuprate sup
erconductors.
