The Institute functions under the guidance of a council of author- 
ized representatives of its member nations, meeting annually to confirm both 
administrative and financial structure. At all other times, administration 
is performed by a directorial staff comprising of a Director, elected for a 
term of three years, two Vice Directors, elected for terms of two years, 
and a Scientific Council, which decides upon the research program and issues 
periodic progress reports. Each member nation contributes financially to 
the maintenance of the Institute (roughly, U.S.S.R. = 75 per cent; China - 
20 per cent; other countries - 5 per cent), and each has equal voice in 
decision making. Other countries can petition for membership and be elected 
by vote of the charter group. 
The Institute confers the Degrees of Doctor and Candidate. Scien- 
tific studies are published in technical journals and reported at meetings; 
copies of all finished studies are supplied to member nations. 
Originally, about 100 scientific collaborators were working at the 
Institute; by 1959, 420 professional and 1,400 other personnel were 
employed. 
The Institute's development was aided by the U.S.S.R., which 
donated the following facilities as the technical basis for its growth: (a) 
The Institute of Nuclear Problems, Academy of Sciences, U.S.S.R. (with a 
synchrocyclotron producing 680,000,000 electron volts), and (b) the Electro- 
physical Laboratory, Academy of Sciences, U.S.S.R. (with a proton synchro- 
tron producing 10,000,000 electron volts). Five laboratories were organized 
and staffed, and two more were projected. In an address commemorating the 
fifth anniversary of the Institute, the Director summarized laboratories’ 
accomplishments: 
(1) Laboratory for Nuclear Problems. Studies have been concerned 
primarily with the investigation of pion-nucleon interaction at 
several 100 Mev. 
(2) High-Energy Laboratory. Among their more important studies 
was the discovery of the anti-sigma-minus-hyperon (> -hyperon), 
announced in 1960. 
(3) Laboratory for Neutron Physics. This group has taken over the 
further development and construction of a pulsed fast-neutron 
reactor designed by the Institute of Physics of the State Committee 
for Application of Atomic Energy. The reactor is unique in that it 
operates periodically in a supercritical regime. 
(4) Laboratory for Nuclear Reactions. An accelerator for multi- 
charged ions has been installed. Investigations have considered 
the interaction of heavy ions with nuclei; _the synthesis of 
element 102 and the development of its 102 isotope have been 
accomplished.
