256RF c  {+260}Sg assignment: {+207}Pb({+54}Cr,n), {+208}Pb({+54}Cr,2n); parent
256RF2c  of {+256}Rf (1984De07,1984Og03,1985Mu11)
256RF c  1985Mu11: measured E|a, I|a, half-life
256RF c  2009He20: {+260}Sg produced in the {+208}Pb({+54}Cr,2n) and
256RF2c  {+207}Pb({+54}Cr,n) reactions with the {+54}Cr beam delivered by the
256RF3c  charge state injector of the UNILAC accelerator at GSI Darmstadt.
256RF4c  Evaporation residues were separated by the velocity filter SHIP and
256RF5c  implanted into a 16-strip Si PIPS detector. A box of six Si-wafers was
256RF6c  used to measure escaping |a-particles. A Ge clover detector consisting
256RF7c  of four crystals was used to measure |g rays in coincidence with
256RF8c  particles. Measured E|a, E|g, half-lives, |s.
