“…For the discovery of elements 104-113 [1][2][3][4][5][6][7][8][9][10][11][12] proton number (Z) and mass number (A) assignments have been made by observing the decay of the parent (new element) nucleus followed by the decay of daughter nuclei with well-established Z and A. These daughter decays have characteristic decay energies and half-lives.…”

Proton number, Z, and mass number,A, assignments for newly discovered heavy element nuclides have historically been made by observing decay to a daughter with well-established Z and A, and then observing the well-know decay of that daughter. For all of the new superheavy element isotopes observed in 48 Ca irradiations of actinide targets, this correlation technique has not been possible, because the -decay chains end in spontaneous fission of previously unknown isotopes. Consequently, Z and A assignments have been made by less-direct means. The superheavy element Z and A assignment methods are summarized, and possibilities for how they may be incorrect are explored. While it is highly likely that most of the superheavy element Z and A assignments are correct, there is a real need for a direct proof. How SHE Z and A assignments have been madeFor the SHE isotopes produced in 48 Ca irradiation of actinide targets, and all of the daughter isotopes resulting from successive -decays, experimenters have resorted to lessdirect means of Z and A assignment. These less-direct means are excitation functions, cross bombardments, and decay systematics. a

Ghiorso) of the aqueous chemistry of rutherfordium have shown it to behave differently than the heavy actinides.…”
