Abstract
Within the Eliashberg theory we present an analysis of the electron-ph onon coupling in the compound Ba0.7K0.3BiO3 This analysis has been car ried out evaluating the isotope coefficient (alpha), using the Rainer and Culetto approach and the electron-phonon spectra alpha(2)(omega)F( omega) as calculated by Shirai et al. for the oxide superconductor Ba0 .7K0.3BiO3 With numerical calculations of some important BCS-ratios an d the analysis of the isotope coefficient in this bismuthate, we outli ned the importance of the electron-phonon coupling in this oxide super conductor.
