✦ Synopsis

The resistivity of single crystals of the cubic high temperature superconductor Ba K BiO with T =30 K has been measured in the tempera-0.60.4 3 C ture range from 4.2 to 300 K. The experimental curve is well approximated in the framework of the classical electron-phonon model of resistivity by the Gruneisen type dependence using the phonon spectrum in the form of an acoustical branch and a widely separated narrow optical peak.
