247FM c  2006He27: {+251}No produced by the {+206}Pb({+48}Ca,3n) reaction at
247FM2c  E=4.80 MeV/nucleon {+48} beam at UNILAC accelerator at GSI, and from
247FM3c  |a decay of {+255}Rf.  Reaction products were separated from the
247FM4c  primary beam by the SHIP velocity filter and implanted into a
247FM4c  position-sensitive 16-strip PIPS detector.

247FM cA E$Three types of uncertainties are combined in quadrature:
247FM2cA statistical uncertainty of 4-8 keV; systematic uncertainty of 15 keV
247FM3cA from calibration methods/standards; uncertainty of 3 keV due to
247FM4cA reproducibility of an |a peak energy.
