چکیده:
The purpose of this paper was to study and map the intellectual structure of Iranian
physicists using author co-citation technique during 1990-2009. The results of the
study showed that Iranian physicists have produced 6290 documents indexed in
Science Citation Index (SciSearch) during the studied period. Publication counts
have grown at an approximate rate of 24/70 % per year. Setare M.R. with 121
documents was the most productive Iranian author in this study. Applied Physics,
with1564 documents was the most interesting subject area for the Iranian
physicists. We identified 42 Iranian and international physicists who were highly
co-cited in 6290 documents during the studied period. Using principal components
analysis, 8 subject factors were extracted. The subject areas of factors were in:
"Physics, Particles & Fields", "Astronomy & Astrophysics", “Physics,
Mathematical", “Physics, Multidisciplinary", "Physics, Nuclear", "Cosmology",
"Physics, Atomic, Molecular & Chemical", and "Physics, Fluids & Plasmas". The
PFNet map of the intellectual structure of Iranian physicists in SciSearch during
1990-2009 showed a central subject area in "Physics, Particles & Field" with
Witten E. as its focal author. The other clusters were rooted in this essential cluster.

com Abstract The purpose of this paper was to study and map the intellectual structure of Iranian physicists using author co-citation technique during 1990-2009.
The PFNet map of the intellectual structure of Iranian physicists in SciSearch during 1990-2009 showed a central subject area in "Physics, Particles & Field" with Witten E.
Different Studies show the rapid growth of scientific research outputs in Iran (ScienceWatche, 2003; Wilson & Osareh, 2003; Moin, Mahmoudi, Rezaei, 2007).
Also on the one hand, some studies show that in the national level Physics ranks 2’d among the basic sciences in terms of output in SCI (Mehrdad, Heydari, Sarbolouki & Etemad, 2004) and on the other hand, Physics has been one of the standard fields in publication, citation and co- authorship comparisons of nations, national groups and major regions for the last two decades (Uzun, 1996).
S. Karamustafaoglu (2007) studied the citation rates and characteristics of 466 Turkish Physics publications that appeared in the research journals listed in the Science Citation Index (SCI) for the period 1983-2003.
Osareh and McCain (2008) studied the structure of Iranian Chemistry research using author co-citation technique.
Soheili, Osareh & khademi (2011) studied intellectual structure of Iranian Biologist outputs in Science Citation Index (SciSearch) during 1990-2008.
Aims and objectives The purpose of this article is to study and map the intellectual structure of Iranian physicists' scientific outputs indexed in SciSearch during 1990-2009 using co-citation analysis.
Intellectual structure map for highly cited authors in Iranian physics documents during 1990-2009 Second cluster is in Astronomy & Astrophysics.
