  The creation of transuranium nuclides under pulsed neutron fluxes of
thermonuclear explosions is investigated within the kinetic model of the
astrophysical r process, taking into account the time dependence of the
external parameters and the processes accompanying the beta decay of
neutron-rich nuclei. Time-dependent neutron fluxes in the interval ~ 10e-6 s
were modeled within the framework of the developed adiabatic binary model. The
probabilities of beta-delayed processes were calculated on the base of the
microscopic theory of finite Fermi systems. Calculations of transuranium
nuclides yields Y(A) are made for three experimental USA thermonuclear
explosions "Mike" (YM), "Par" (YP) and "Barbel" (YB). The root-mean-square
deviations of the calculations compare to the experimental data (r.m.s.) are
91% for YM, 33% for YP, 29% for YB , which are significantly lower than for
other known calculations. The exponential approximation of the experimental
dependences Y(A) is carried out and the obtained values of r.m.s are equal to
56%, 86.8% and 60.2% for YM, YP and YB correspondingly, which is better or
comparable with other calculations. An even-odd anomaly in the observed yields
of heavy nuclei is explained by the predominant influence of processes
accompanying the beta decay of heavy neutron-excess isotopes.
