Production of the New Element 102

Ternary fission of 260No in collinear configuration

“…Even the earlier report on No [26] was not confirmed later, but the name Nobelium was suggested in this work [27]. So far, thirteen No radioisotopes with mass numbers A=249 260 and A=262 have been identified [28].…”

Atom-at-a-Time Chemistry

“…(Although an earlier reported discovery [7] of No utilized chemical separation, the procedure was not definitive enough to exclude non-actinide activities and also did not allow for the possibility of the divalent oxidation state of No being the most stable in aqueous solution.) Isotopes of No were produced [8] via 244,245 Cm( 12 C,xn) reactions and positive identification was based on the alpha daughter correlation technique.…”

Discovery of isotopes of elements with

“…[59] and, especially, [60], both submitted in 1965, give conclusive evidence that element 102 had been produced" [11,45]. Fields et al had suggest the name nobelium "We suggest the name nobelium, symbol No, for the new element in recognition of Alfred Nobel's support of scientific research and after the institute where the work was done" [57]. Although this original report was not correct the name was continued to be used and officially accepted in 1997 [61][62][63][64].…”
