Abstract : This paper attempts to highlight quantitatively the growth and development of world literature on Bhabha Scattering in terms of publication output as per International Nuclear Information System (INIS) (1970-2008), Science Citation Index (1982-2008), and INSPEC (1969-2008) databases. During 1969-2008 a total of 1305 papers were published by the scientists in the field Bhabha Scattering. The average number of papers published per year was 32.62. The highest numbers of papers 66, were published in 1988 and 1997, respectively. There were 47 countries involved in the research in this field. Germany is the top producing country with 421 papers followed by USA with 420 papers, Italy with 293 papers, and Switzerland with 263 papers. Authorship and collaboration trends were towards multi-authored papers. There were 888 (68.05 percent) collaborative papers. Istituto Nazionale di Fisica Nucleare (INFN), Italy, topped the list with 256 papers followed by European Organisation for Nuclear Research (CERN), Switzerland, with 243 papers. The most preferred journals by the scientists were: Physics Letters-B with 188 papers, Nuclear Physics-B with 91 papers, and Physical Review-D with 90 papers. The high frequency keywords were: Bhabha scattering (731), radiative corrections (215), annihilation (214), electrons (208), positrons (205), and pair production (202).

Abstract : This paper attempts to highlight quantitatively the growth and development of Indian research in the field of Nanoscience and Nanotechnology in terms of publication output as per Science Citation Index (1982-2008). The whole database contains 296072 records on the subject and among them USA topped the list with 84561 (28.56 per cent) followed by, China with 43393 (14.66 per cent) publications, Japan with 32431 (10.95 per cent) publications, Germany with 28065 (9.48 per cent) publications, France with 18141 (6.13 per cent) publications, and England with 13850 (4.68 per cent) publications. During 1982-2008, a total of 8326 (2.81 per cent) papers were published by the Indian scientists in the field. The yearly average number of documents published was 308.37. The highest numbers of publications (1890) were published in 2008. The premier Indian institutes engaged in Nanoscience and Nanotechnology research were: Indian Institute of Science (IISc), Bangaluru with 723 publications followed by IIT Kharagpur with 606 publications; National Chemical Laboratories (NCL), Pune with 589 publications; Indian Association for the Cultivation of science (IACS), Kolkata with 563 publications; and BARC, Mumbai with 434 publications. Major portion of the publications (96.36 per cent) were written in collaboration with more than one authors. India had collaboration with 67 other countries in the field. C.N.R. Rao, M. Sastry and S. Chaudhuri were the three leading researchers in the field. Researchers from Indian Institute of Science, Bangalore and Jawaharlal Nehru Centre for Advanced Scientific Research, Bangalore had most number of collaborative publications. When collaboration among institutes situated in different Indian cities was taken into consideration, Bangaluru and Kolkata were found to have the highest number of collaborative publications. Karnataka and West Bengal, the parent states of these cities were the states with the most collaborative publications in Nanoscience and Nanotechnology research. USA, Germany, and Japan had more number of collaborative publications with India. The most preferred journals for publishing the articles by the scientists were: Journal of Applied Physics (293), Journal of Nanoscience and Nanotechnology (285), Applied Physics Letters (243), Materials Letters (232), Physical Review B (232), Nanotechnology (194), and Langmuir (182). The highly occurred keywords in SCI records were: Nanoparticles (1244); Particles (756); Films (589); Growth (513); Nanocrystals (501); Thin-Films (484); Nanostructures (427); Optical-Properties (410); Nanocomposites (401); etc.
