193TL C Sources from {+14}N bombardments of Ir, {+16}O bombardments of
193TL2C Re, and {+20}Ne bombardments of {+181}Ta, mass separation;
193TL3C measured E|a, I|a, time-sequential |a and |g spectra.

193TL CA E$From 1991Ry01, based on 5780 {I5} (1985Co06), 5770 {I10} (1974Le02),
193TL2CA 5770 {I10} (1972Ga27); other: 1970Ta14
193TL CA HF r{-0}({+193}Tl)=1.50 {I1}
193TLxCA Value for r{-0} suggested by neighboring Pb isotone, with
193TLxCA r{-0}({+194}Pb)=1.496 3 (1998Ak04)
193TLxCA The quoted radius value gives HF=0.15 for this
193TL2CA decay. Since HF<<1 is not expected in odd-^A nuclei, one must
193TL3CA question the input to HF calculation. The two uncertain quantities
193TL4CA are the nuclear radius, r{-0}, and %|a from {+197}Bi. In order to
193TL5CA obtain an HF|?1 one would have to use r{-0}=1.59 which is unreasonably
193TL6CA large for this region. Using r{-0}=1.49,
193TL7CA based on overall systematic trends for r{-0}, an alpha
193TLxCA branch of %|a|?12 gives a HF|?1.0.
193TL9CA It seems, therefore, that %|a=55 {I40} quoted in
193TLACA 1985Co06 may be too large.
