“…Microphotograph of a part of a severely damaged 244 PuO 2 target after intense irradiations (illuminated from the back side) [51]. A: Macroscopic hole in the target material layer and in the backing; B: Target material is still intact, the target backing material is burned, presumably due to the reaction with the target material.…”

Chemistry has arrived on the shore of the Island of Stability with the first chemical investigation of the superheavy elements Cn, 113, and 114. The results of three experimental series leading to first measured thermodynamic data and qualitatively evaluated chemical properties for these elements are described. An interesting volatile compound class has been observed in the on-line experiments for the elements Bi and Po. Hence, an exciting chemical study of their heavier transactinide homologues, elements 115 and 116 is suggested.

“…A fundamentally new approach to the preparation of thermal stable and radiation resistive intermetallic targets was demonstrated by I. Usoltsev [20]. The preparation process comprises two steps: the target material ( 243 Am) is electroplated on a noble metal (Pd) surface; the foil with the deposited material is heated in a hydrogen flow, forming an intermetallic compound.…”

“…The application of neutron activation analysis, scanning electron microscope, back scattering of protons, and radiographic imaging for the characterization of deposited layers of lanthanide and actinide elements for elaboration of new methods and study effects of irradiation on morphological and chemical composition of targets, is described in [21][22][23]. The earlier cited publications [13,17,18,20] contain more detailed information on specific experimental procedures.…”

Over the past decade, numerous isotopes of superheavy elements with Z = 112-118 have been synthesized. Production cross sections for these species are in the range of a few picobarns (1 pb = 10 -36 cm 2 ) or less. To get access to heavier nuclides and carry out a detailed study on their properties, a sufficient increase of the overall sensitivity of experiments is needed. The direct solution consist in increasing of the beam intensity and development of separators providing the necessary background suppression. Therefore, the design of high power radioactive targets becomes a key problem. In this report, we consider specific requirements to the development of targets for the synthesis of superheavy elements.
