    Notes: [Auszug] The synthesis, via nuclear fusion reactions, of elements heavier than the actinides, allows one to probe the limits of the periodic table as a means of classifying the elements. In particular, deviations in the periodicity of chemical properties for the heaviest elements are predicted as a ...

    Notes: Abstract Today we know 111 chemical elements. The heaviest among the 19 man-made transuranium elements are synthesized in fusion reactions between heavy-ion projectiles and lead/bismuth-or actinide-targets. From extrapolations of known cross sections we can assume that in both approaches still heavier elements are accessible. Reactions withi lead and bismuth targets will yield higher cross sections at the picobarn level. They are best suited to synthesize new, deformed superheavy elements around the neutron-shell at N=162. Actinide-target based reactions will exhibit lower cross sections in this region but they bare the potential to produce more neutron-rich nuclei closer to the center of spherical superheavy nuclei at Z=114 and N=184. Transfer reactions are a potential source of superheavy elements which has not been fully exploited yet. Recently suggested new paths of synthesis reactions await experimental tests.
