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}.
