Q(β-)=-2.67×103 keV SYS(n)= 6.57×103 keV SYS(p)= 5.3×103 keV SYQ(α)= 7.70×103 keV SY
Reference: 2012WA38

General Comments:

Assignment: 254Es(95-MeV 18O,x), 254Es(73-MeV 13C,x), 254Es(125-MeV 22Ne,x); the production cross section in 254Es(18O,x) reaction agrees with expectation from extrapolation of yield curve (1985So03). Assignment to 260No is tentative.

Angular distribution of fission fragments following 238U(22Ne) reaction was measured by 1986Ka12.

For calculated fission-barriers, see, for example, 1976Iw02, 1983Cw01, 1985Lo05, 1992Bh03.
