Abstract

The formation of transuranium nuclides in pulsed neutron fluxes of thermo-nuclear explosions is investigated in the kinetic model of the astrophysical r-process, taking into account time dependence of the external parameters and including the processes accompanying the β-decay of neutron-rich nuclei. Time-dependent neutron fluxes in the interval ∼ 10−6 s were modeled within the developed adiabatic binary model. Probabilities of β-delayed processes were calculated using the microsco-pic theory of finite Fermi systems. Calculations of the yields of transuranium nuclides Y(A) are made for three experimental USA thermonuclear explosions ”Mike” (Y
