180PT c  {+184}Hg activity produced in {+148}Nd({+40}Ca,4n), E({+40}Ca)=200
180PT2c  MeV. Measured E|a, I|a, E(ce), |a-ce-t and |a-x-ray-t coincidences
180PT3c  using a PIPS detector for |a's, a LEPS detector for x-rays and a
180PT4c  plastic scintillator for ce's.
180PT c  The absolute intensity of the 5535-keV |a was obtained by 1970Ha18 to
180PT2c  be 1.25% {I20} from their measurements of |a/K x-ray ratio. The
180PT3c  measured I(K| x-ray) was corrected by 1970Ha18 for K| x-ray's due to
180PT4c  conversion electrons.
180PT c  In agreement with this intensity, 1980Sc09 obtained I|a(5535|a)=1.11%
180PT2c  {I6} from comparison of the intensities of parent and daughter
180PT3c  activities in the same spectrum. The |a branchings used for the
180PT4c  daughter nuclei are not given in 1980Sc09. A 30% correction was
180PT5c  applied by 1980Sc09 to the daughter line for the escaped recoiled
180PT6c  nuclei.
180PT c  In deducing the total |a branching, I|a(5535|a)=1.25% {I20} is
180PT2c  adopted here and the 5380 and 5055 |a intensities are added to
180PT3c  I|a(5535|a). I|a(5380|a)/I|a(5535|a)=40 {I8}/9960 {I8}, as adopted in
180PT4c  1989Fi11, and I|a(5055|a)=0.0020% {I4}, measured by 1994Wa13, are
180PT5c  used.
