211FR c 2004Ku24:{+215}Ac isotope produced in the reaction
211FR2c {+209}Bi({+12}C,6n) at E=7.1, 8.6 and 9.1 MeV/nucleon. Evaporation
211FR3c residues separated from {+12}C beam by SHIP velocity filter. Measured
211FR4c E|g, E|a, I|g, I|a, |g|a coin with a position-sensitive 16-strip PIPS
211FR5c Si detector and an HPGe detector. In a later experiment, the latter
211FR6c was replaced by a Ge Clover detector consisting of four crystals to
211FR7c measure |g-ray multiplicity. The Si detector had FWHM=22 keV at 8 MeV.
211FR c 2000He17: {+215}Ac recoils from {+12}C on {+209}Bi (E=100 MeV) were
211FR2c separated from the beam using a velocity filter and implanted into a
211FR3c position-sensitive semiconductor detector. Measured E|a, |a|g coin
211FR4c (2000He17). Data in this Ref. will not be used since it is
211FR5c superseded by 2004Ku24 (same group)
211FR cA HF$ Using r{-0}({+211}Fr=1.4606 {I41}; interpolated value deduced from
211FR2cA r{-0}({+212}Ra)=1.466 {I6}, and r{-0}({+210}Rn)=1.4552 {I21}
211FRxcA (1998Ak04).
211FR cA IA$2004Ku24 indicate that |a-intensities are probably underestimated
211FR2cA as losses due to electron summing were not taken into account.
211FR cA HF$ Deduced using ALPHAD computer code. Values from 2004Ku24
211FR2cA are given under comments
211FR cG RI$ Branching ratios given in 2004Ku24 converted to absolute I|g
211FR cG M,MR$ From Adopted Gammas
211FR cL J$Assignments based upon the tentative multipolarity assignment for
211FR2cL the 110 |g-ray, comparison with isotones {+207}Bi and {+209}At,
211FR3cL hindrance factors, and on the (11/2-) and (13/2-) spin-parity
211FR4cL assignments to 583 and 653 levels, respectively (from literature).
