OSTI ID:5363293
Phonon density-of-states (DOS) of insulating BaBiO{sub 3} and superconducting Ba{sub 0.6}K{sub 0.4}BiO{sub 3} is studied using effective interaction potentials and molecular dynamics (MD) method. MD Results are in good agreement with the inelastic neutron scattering and electron tunneling experiments. Calculated oxygen isotope effect using the Eliashberg gap equations is also in good agreement with the experiments. Cumulative evidence based on the neutron scattering, tunneling, and the isotope effect suggests that this material is a normal BCS electron-phonon superconductor. 11 refs. , 3 figs., 2 tabs.
