Description
Summary:•Model of isotope creation under the condition of artificial explosive nucleosynthesis.•Relation of isotope yields as a signature of the explosive neutron fluence. Artificial creation of isotopes under extremal neutron fluxes at nuclear explosions allowed to obtain the identifiable quantities of transuraniums with neutron excess up to 19. The analysis of yield relations between produced neighboring isotopes (with A-atomic mass pairs 245/244, 246/245, 247/246) allows to evaluate the reached neutron fluences (in units of 1024 neutron/cm2) in the volume of the irradiated target. The obtained results (basing on the developed dynamical model for transuranium isotope generation under pulse nucleosynthesis) for large scale experiments allow to consider the dependence of isotope relations from the fluence as approximately linear within obtained values of fluences up to ∼2.5 × 1024 neutron/cm2.
