Scientometric Portrait of P. K. Iyengar

P.K. Iyengar, the well known nuclear physicist is widely recognised as a very successful scientist. His publications were analysed by year, domain, collaboration pattern, channels of communications used, keywords etc. The results indicate that the temporal variation of his productivity and of the types of papers published by him are of such a nature that he is eminently qualified to be a role model for the younger generation to emulate. By the end of 1992, he has to his credit 74 papers in Neutron and Solid State Physics; 26 papers in Mossbauer Spectroscopy, 34 papers in Reactor Physics, Fusion, and Cold Fusion; 21 papers in Nuclear Power, and 27 papers of general popular interest. The period 1972-76, when Iyengar was 41-45 years age, was his most productive period with highest publication activity. Publication density was 1.9 and publication concentration was 21.87. Bibliograph of individual scientist does not follow Bradford's law. Productivity exceeds the conventional expectations of 80/20 rule.
