148DY c  T{-1/2}({+152}Er)=10.3 s {I1}, measured by 1982Bo04 and adopted by
148DY2c  1996Ar09, is used in calculations here.
148DY c
148DY c  %|a=91 {I4} is used in calculations. This branching is an unweighted
148DY2c  average of %|a=93 {I4} (1979Ho10), %|a=94 {I4} (1987To02) and %|a=86
148DY3c  {I4} (1987To02), determined by counting different |g's and the 4804|a.
148DY4c  %|a=90 {I4} is adopted by 1996Ar09 from the |a branchings
148DY5c  obtained by 1987To02.

148DY cA E         recommended by 1991Ry01 from the measured energies of
148DY2cA 4800 {I10} (1970To16), 4806 {I10} (1977Ha48), 4804 {I2} (1981De22),
148DY3cA 4805 {I3} (1982Bo04), 4809 {I10} (1983Ml01). The original energies are
148DY4cA adjusted for changes in calibration energies, as recommended by
148DYxcA 1991Ry01.
148DY cA IA        only one |a group was observed. An upper limit of
148DY2cA 6.8|*10{+-10} per 100 |a decays is calculated for an unobserved
148DY3cA 3171-keV |a to the 1677.3-keV, 2+ state in {+148}Dy by requiring
148DYxcA HF(3171|a)>1.
