摘要

Presented are the results of experimental study on synthesis of wide range of isotopes in a cold superdense monoelemental plasma. Initial conditions necessary for plasma bunch formation were provided by specially organized coherent impact on a solid target with a total energy up to 1 kJ. More than 3500 shots were performed with various targets made of light, medium and heavy elements. Products of nucleosynthesis in the target precipitated on the inner surface of a concentrator surrounded the target and on an attached accumulating screen. Subsequent analysis of the products reveals presence of a wide range of elements. Elements with nuclei three and more times heavier than the nucleus of the initial element are detected in the products. The isotopic compositions of the produced elements differ from spot to spot and significantly differ from the natural one. In the products generated in the heavy element targets presence of unknown superheavy elements is detected with several different spectroscopic methods.
