246CF c 2006Fo02: {+250}Fm was produced from the |e decay of {+250}Md.
246CF2c The study of the {+262}Bh decay chain was performed at Berkeley
246CF3c Gas-filled Separator at Lawrence Berkeley Laboratory. Measurements
246CF4c were performed with Si detectors and multiwire proportional counter.
246CF5c Measured E|a and T{-1/2}
246CF c 1981Mu06: {+250}Fm was produced from the |e decay of {+250}Md.
246CF2c The study of the decay chain was performed at UNILAC linear accelerator
246CF3c at GSI. Measurements were done with surface barrier detectors.
246CF4c Measured E|a and T{-1/2}
246CF c 1977Be36: {+250}Fm was produced from the |e decay of {+250}Md.
246CF2c The study of the decay chain was performed at the Oak Ridge
246CF3c Isochronous Cyclotron (ORIC) at ORNL. Measurements were done with
246CF4c surface barrier detectors. Measured E|a
246CF c 1966Ak01: {+250}Fm produced from {+238}U({+16}O,6n). |a
246CF2c decay was measured with (Si+Au) detectors. Measured E|a and T{-1/2}.

246CF cA IA$Calculated by evaluator from HF(7396)|?3.4 estimated from
246CF2cA systematics of neighboring even-even Cf nuclides ({+242}Cf,
246CF3cA {+244}Cf, {+248}Cf, {+250}Cf).
246CF cA HF$The nuclear radius parameter r{-0}({+246}Cf)=1.4776 {I41}
246CF2cA is deduced by assuming HF=1.0 for the ground-state to
246CF3cA ground-state alpha decay branch.
