Abstract
In bombardments of Cm-248 with Ne-22 we discovered two new isotopes, ( 265)106 and (266)106, by establishing genetic links between their a de cays and spontaneous fussion (SF) or alpha decays of the daughter nucl ides. We measured E(alpha) = 8.63 +/- 0.05 MeV for (266)106 and a half -life of 1.2 s for its daughter (262)104. For (265)106 we measured E(a lpha) = 8.71 to 8.91 MeV. From these a energies we estimated alpha hal f-lives of 10-30 s for (266)106 and 2-30 s for (265)106. We estimated SF branches of 50% or less for both isotopes. The decay properties of (266)106 establish the existence of enhanced nuclear stability near th e predicted deformed shells N = 162 and Z = 108.
