Abstract
We present results of a thermodynamic analysis for the superconductors compounds BaPb0.7Bi0.3O3 and Ba0.7K0.3BiO3 are calculated making use of the Eliashberg theory spectra alpha(2)(omega)F(omega) as calculated by Shirai et al. BaPb0.7Bi0.3O3, several models of the alpha(2)(omega )F(omega) were studied looking for a better agreement with experimenta l data. The a simple constant scaling (C = 1.25) of the Shirai's spect ra, The functional derivative of the deviation function D(t) with resp ect to changes in alpha(2)(omega)F(omega) is also calculated.
