Georg(e) Placzek: a bibliometric study of his scientific production and its impact

Abstract

The availability of a number of databases, in particular the Science Citation Index (SCI), have encouraged the development and use of bibliometric techniques to analyze and evaluate the production and impact of scientists. To avoid pitfalls and their sometimes serious consequences, however, considerable experience with the method is needed. The case of George Placzek appears as an excellent one to illustrate the procedure and its problems. Placzeks work covered a broad range of topics, including optical and neutron spectroscopy, neutron diffusion, nuclear reactions, and nuclear energy. He worked in a large number of places with some of the most outstanding collaborators and also as sole author during his short professional life. His publications appeared in regular, so-called source journals, in books, lecture notes and also internal reports which were classified till several years after the end of the war. In this article we analyze Placzeks work and its impact with the aim of illustrating the power and virtues of bibliometric techniques and their pitfalls.
