Аннотация:Various relational nuclear databases produced at the MSU SINP CDFE are widely used for both scientific research and solving of many educational tasks primarily in coordination with the Chair of General Nuclear Physics of the MSU Physics Faculty. Using those databases powerful and flexible Search Engines students have access to modern accurate and reliable international nuclear data funds. The databases produced at the CDFE contain various data on the nuclei themselves, their shapes and sizes, their levels and transitions between them, various nuclear reactions and radioactive decays features, parameters of giant dipole resonances, correspondent bibliography information.
Useful information on main nucleus parameters were spread before between many sources and efficiency of their using was not enough. Because of that the new “Nucleus Ground and Isomeric State Parameters” database (http://cdfe.sinp.msu.ru/services/gsp.ru.html) was produced combining important nucleus data from several sources and therefore giving to one convenient and comfortable possibilities for various data combined processing.
Those parameters of both ground and isomeric states of all known till now atomic nuclei (Z = 1 – 118) are:
- Abundance of stable isotope or half of time of unstable isotope;
- Spin and parity of ground or isomeric state;
- Energy of isomeric state;
- Nucleus atomic mass, mass excess and binding energy [3];
- Nucleus decay modes [4];
- Nucleon (p, n) separation energy;
- Nucleus decay (e-, e+, , ) energy.
