220RA c  1992Ru01: {+220}Fr activity was produced by bombarding {+232}Th with
220RA2c  280-MeV {+3}He beam, and mass separated by the ISOCELE II on-line mass
220RA3c  separator. Measured |b{+-}, |g rays, |g|g coin. Detectors: 4|p plastic
220RA4c  scintillator for |b{+-} particles, and two Ge(Li) (planner and coaxial)
220RA5c  for |g ray detection.

220RA cN NR$approximate normalization based on I|g(178)<0.05% (1973ChZH) and
220RA2cN 0.35% |b decay branching of {+220}Fr. |SI|g(1+|a)=0.35 {I5} to the g.s.
220RA3cN yields a normalization factor of 0.0014 {I4}, which results in a zero
220RA4cN |b feeding from J{+p}({+220}Fr)=1+ to J{+p}(g.s. of {+220}Ra)=0+.
220RA5cN For an 1+ to 0+ transition (allowed), |b feeding can be
220RA6cN expected and so the factor based on |SI|g(1+|a) was rejected.
