  In the present work carried out at the Electrodynamics Laboratory Proton-21
with the use of X-ray electron probe microanalysis (XEPMA) and glow-discharge
mass spectrometry (GDMS) techniques, we study the chemical composition of a
substance formed as a result of the explosion-induced compression of solid
targets and deposited on the surfaces of accumulating screens. We established
that the explosion products contain chemical elements which were not included
in the composition of the initial materials of targets and accumulating screens
or were included in them as impurities in quantities by 3...7 and more orders
in magnitude less than those detected after the experiment. We conclude that
the regular appearance of chemical elements, which were not included in the
composition of the initial materials of targets and accumulating screens, in
the explosion products is the consequence of a nuclear transformation of a part
of their material, i.e., is the fact testifying to both the running of the
nucleosynthesis reactions upon the explosion-induced destruction of targets and
to the first realized possibility of controlled creation of the conditions for
their running in a laboratory setup.
