Abstract

RECENTLY I published some contributions1,2 on the problem of the structure of the Earth's core. In the course of this work a considerable amount of observational material on the seismic core phase PKP was examined and empirical seismological travel-time tables for two branches of the PKP curve were derived from the observations. A number of seismologists have suggested that it would be useful to them if such tables were published.
