چکیده
1 Energy release in alpha-decay 2 Consider a nucleus which is stable against decay by proton or neutron emission { the least bound nucleon still has (say) several MeV of binding energy. This nucleus may nevertheless still be able to decay by using the fact that if it can emit an alpha-particle (2He), it can use the binding energy of the alpha to supply the energy needed for the escape. That is, the available energy release in alpha decay is

Calculated nuclide production yields in relativistic collisions of ssile nuclei ?
A model calculation is presented which predicts the complex nuclide distribution resulting from peripheral relativistic heavy-ion collisions involving ssile nuclei. The model is based on a modern version of the abrasion-ablation model which describes the formation of excited prefragments due to the nuclear collisions and their consecutive decay. The competition between the evaporation of di ere...
متن کاملReview of Risks from Tritium Report of the independent Advisory Group on Ionising Radiation
The cover shows the sun over a nuclear power station. Tritium is generated by nuclear fusion reactions in the sun and would be generated in terrestrial nuclear fusion power production. It is also produced as part of the fuel cycle in current nuclear fi ssion power production and has several uses in industry.

Half lives alpha decay is the one of the most important parameters used for describing nuclear structure in nuclear dynamics; over the years, many studies have been done in this area. In this study, by using semi-empirical methods such as Viola-Seaborg (VSS), Royer, Parkhomenko and Sobiczewski (PSM), Brown, New Geiger-Nuttall (NGN), Poenaru et al. (UNIV) and Universal Decay Law (UDL), the half ...
متن کاملNuclear Structure and Transfer Reactions of Dripline Nuclei
Systematic studies of isotopic chains including nuclides from the proton to the neutron dripline are an ideal testing ground for nuclear structure theory. Results of Hartree{Fockcalculationsfor oxygen and tin isotopes are discussed. Exploratory calculations for single nucleon transfer reactions on dripline nuclei are presented. In inverse kinematics transfer reactions of ssion fragments the dri...

In this paper, the nonlinear dynamic system of equations, a type of nuclear ssion reactor is solved analytically and numerically. Considering that the direct solution of three-dimensional dynamical systems analysis and more in order to determine the stability and instability, in terms of algebraicsystems is dicult. Using certain situations in mathematics called Hurwitz criterion, Necessary and ...
