Fellow Soviet scientists Igor Y. Tamm and Ilya M. Frank investigated the phenomenon from which the Cherenkov counter was developed. Extensive use of this Cherenkov detector was later made in applications of experimental nuclear and particle physics. For their work, the trio shared the 1958 Nobel Prize for Physics. |
