Discovery of Enhanced Nuclear Stability near the Deformed Shells $N = 162$ and $Z = 108$

In bombardments of

{}^{248}{Cm}

with

{}^{22}{Ne}

we discovered two new isotopes,

{}^{265}106

and

{}^{266}106

, by establishing genetic links between their

α

decays and spontaneous fussion (SF) or

α

decays of the daughter nuclides. We measured

E_{α} = 8.63 \pm 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_{α} = 8.71 to 8.91

MeV. From these

α

energies we estimated

α

half-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 the predicted deformed shells

N = 162

and

Z = 108
