Ivan Aničin, (born 25 March 1944 in Bor, Serbia, Yugoslavia, died 2 April 2016) was Yugoslav and Serbian nuclear physicist, particle physicist, astrophysicist, and cosmologist, university Full Professor and Distinguished (teaching/research) Professor of scientific institutes in Belgrade (Serbia), Bristol (United Kingdom), Grenoble (France), and Munich (Germany).

Ivan Aničin was educated in Yugoslavia (Belgrade), United Kingdom (Bristol), France (Grenoble), and Germany (Munich).

[5] His interests and research are in the fields of nuclear spectroscopy of gamma radiation and conversion electrons and their angle correlations, studies of rare and low probability nuclear and fundamental processes (especially neutrinoless double beta decay, non-resonant excitations), detection of solar neutrinos, detection of dark matter, measurements of cosmic radiation, and methodology of experimental nuclear physics in general.

The courses are part of broader Master of Science level at Faculty of Physics, University of Belgrade.

Professor Aničin mentored or was member of degree granting committee of more than 200 MSc, PhD, and Doctor of Sciences in Physics degrees to American, British, Croatian, French, German, Greek, Iraqi, Iranian, Libyan, Montenegrin, Russian, Serbian, Slovenian, Soviet, and Yugoslavian physicists.

He also mentored MSc and Doctor of Sciences in Physics degrees of his colleagues and successors at Faculty of Physics of University of Belgrade: professors Jovan Puzović (at CERN from 2000), and professor Goran Škoro (from 2004 on leave at UK Neutrino Factory).
