- Abstract
- Artificial rapid nucleosynthesis (r-process) in high intensive neutron fluxes of thermonuclear explosions (∼10 n/cm during the time ∼10 s) is investigated within the developed dynamic model. Creation of transuranium nuclides is studied taking into account the time dependence of parameters and processes accompanying the beta-decays of neutron-rich nuclei. The probabilities of beta-delayed processes are calculated basing on the finite Fermi systems theory. Calculations of the transuranium nuclides’ yields Y (A) were carried out for five large-scale explosiveUSA experiments (“Mike”, “Anacostia”, “Par”, “Barbel” and “Vulcan”). It was obtained good or satisfactory agreement with experimental data. Even-odd anomaly in the observed transuranium yields at A > 250 is explained by the effect of processes accompanying the betadecays of heavy neutron-rich isotopes.
