The Joint Institute for Nuclear Research (JINR) is an international intergovernmental scientific research organisation founded 26.03. 1956 by 12 countries of Central and Eastern Europa.
In 1947 a group led by I.V. Kurchatov initiated the construction of charged particle accelerator (680 MeV synchrocyclotron). It was decided that it will be built on the banks of the Volga river - 120 km north of Moscow. The accelerator was completed in 1949 and became the basic facility of the Institute of Nuclear Problems (INP), headed by physicists and M.G. Meshcherjakov and V.P. Dzhelepov. As another institute was established in Dubna Electro-physical Laboratory of the Academy of Sciences of the USSR (EFLAN) led by V.I. Veksler.
In 1954, near Geneva, the European Organization for Nuclear Research (CERN) was established, which unified the efforts of countries in Western Europe towards the study of the fundamental properties of microworld.
In response to the creation of CERN the countries of Central and Eastern Europe founded JINR, which was based on INP and EFLAN institutions already existing in Dubna.
Czechoslovakia was among the founding members of JINR. Czechoslovakia has always had an important position in the JINR, as evidenced by the appointment of a prominent Czechoslovak scientists into management positions, e.g. deputy director of JINR gradually became prof. V. Votruba, prof. I. Úlehla, prof. Č. Šimáně and dr. M. Gmitro or the deputy head of the laboratories became Prof. V. Petržílka, dr. J. Perneger and others.

Project

For the first time, the KLL Auger spectrum of La (Z = 57) following the electron capture decay of radioactive 139,141Ce in a solid source was measured. The all nine basic spectrum components were resolved and their energies and relative intensities were d
