Internal Conversion Processes documents the proceedings of the International Conference on the Internal Conversion Process held at Vanderbilt University, Nashville, Tennessee on May 10-13, 1965.

This compilation discusses the internal conversion theory; experimental methods for the determination of internal conversion coefficients; and conversion electron-gamma directional correlation. Other topics include the application of the internal-external conversion (IEC) method to the lens-type spectrometer; anomalies of E2 conversion coefficients in the deformed-nucleus region; and conversion coefficients of mixed E2-M1 rotational transitions. The anomalous El conversion; internal conversion electrons from primary fission fragments; particle parameters measured in pure transitions; and survey of El transitions in the rare earth region are also discussed in this book.

This publication is a good reference for nuclear physicists and researchers conducting work on the various types of measurements that involve internal conversion electrons.
