The nuclear shell model has been applied to calculate possible gamma decay schemes for neutron-rich nuclei, as well as various information about the individual energy levels within the nucleus. Comparisons will be made to experimental data if it exists. Information calculated about individual decays includes initial and final excitation energies, angular momenta, branching ratio, and mean lifet...

This experiment gives you the opportunity to study high energy photons from radioactive decays. These photons have energies that are characteristic of the specific initialand finalstate nuclear energy levels and therefore provide a means of studying the energy levels (similar to the use of optical photons to study electronic energy levels in atoms), nuclear reactions, and also provide a way to ...

Blackbody radiation BBR shifts of the P0S0 clock transition in the divalent atoms Mg, Ca, Sr, and Yb are evaluated. The dominant electric-dipole contributions are computed using accurate relativistic many-body techniques of atomic structure. At room temperatures, the resulting uncertainties in the E1 BBR shifts are large and substantially affect the projected 10−18 fractional accuracy of the op...

customer activity has received more attention due to the increase of social network applications. moreover, customer activity could be an answer to the research debate about the significant relationship between retention rate and lifetime profitability of customers. several researchers believe that an increase in the retention rate of customers may enhance their customer lifetime value (clv), o...

Today, information networks play an important role in supply chain management. Therefore, in this article, clustering-based routing protocols, which are one of the most important ways to reduce energy consumption in wireless sensor networks, are used to optimize the supply chain informational cloud network. Accordingly, first, a clustering protocol is presented using self-organizing map neu...

For close to half a century nuclear fission has been providing reliable supplies of electricity to the UK, with virtually no emissions of carbon dioxide. Over that period, the UK nuclear industry has avoided the emission of over one and a half billion tonnes of CO2. Yet no nuclear plant has been built in the UK for over two decades even though many of the stations in our current fleet are now w...

Uloženie nukleárneho odpadu vysokého stupňa v Nemecku Nuclear energy is very often used to generate electricity. But first the energy must be released from atoms what can be done in two ways: nuclear fusion and nuclear fission. Nuclear power plants use nuclear fission to produce electrical energy. The electrical energy generated in nuclear power plants does not produce polluting combustion gase...

The Nuclear Energy Agency (NEA) Expert Group on Innovative Structural Materials (EGISM) was established in 2008 under the guidance of Science Committee (NSC). Its objectives are to conduct joint and comparative studies support development, selection characterisation innovative structural materials that can be implemented advanced nuclear fuel cycles, long service lifetime extreme conditions, su...
