159DY D DATA SET PUDATED (NOVEMBER, 2010) BY CW REICH TO INCLUDE REVISED CC
159DY2D VALUES, REVISED RI VALUE FOR THE 57 G, INCLUSION OF K-XRAY
159DY3D INTENSITIES, REVISED NR VALUE, CORRECTED FORMAT PROBLEMS, AND
159DY4D REVISED COMMENTS.
159DY c Isomer produced by {+159}Tb(d,2n) with pulsed beam (1968Bo18,1965Bo22)
159DY2c with E(d)=12~MeV; by {+159}Tb(p,n) (1967Co26,1965Bo22) with
159DY3c E(p)=5-18~MeV, and Gd(|a,xn) (1965Bo22,1968Io01).
159DY c Decay scheme is that of 1968Bo18, plus several |g rays known from
159DY2c {+159}Ho |e decay to depopulate these levels.
159DY d Experimental methods:
159DY d 1965Bo22: From (p,n), (d,2n), and (|A,xn) reactions with pulsed
159DY2d beams. Measured G's with NaI(Tl) detector and ce in magnetic
159DY3d spectrometer. Report EG, IG, K/L, multipolarities for 7 G's.
159DY d 1967Co20: From 159TB(p,n). Report EG and T1/2 of parent level.
159DY d 1967Co26: From (p,n). Report EG, IG, for 7 G's.
159DY d 1968Bo18: From 159TB(d,2n). Measured G and ce singles and ce-G
159DY2d and GG coincidences. Report EG, IG, I(ce), |a{-K}(exp), and
159DY3d |a{-L}(exp) for 11 G's.
159DY d 1968Io01: From (A,xn). Summary, not clear what data are new results.
159DY d 1972AnZK: Abstract, comments on isomerism.
159DY cG $I(K| x ray)=175~{I30} (1968Bo18). Others: 183 (1965Bo22); and 154
159DY2cG (1967Co26), after scaling the published data to make the intensity
159DY3cG scale compatible.
159DY cG E$From 1967Co26, except as otherwise noted. Other: 1965Bo22. For more
159DY2cG precise values, see {+159}Dy Adopted |g radiations.
159DY cG RI$From 1968Bo18, except as otherwise stated. Others: 1965Bo22 and
159DY2cG 1967Co26, which do not give uncertainties. See 1968Bo18 for I(ce) data.
159DY cG M,MR$From {+159}Dy Adopted |g radiations.
159DY cG CC$Values were computed for the more accurate |g-ray energies from the
159DY2cG {+159}Ho |e decay.
159DY cG E(R)$Not seen in isomer decay, but placement established in {+159}Ho |e
159DY2cG decay. E|g, I|g, and I|g(1+|a) from Adopted |g data and
159DY3cG I|g(1+|a)(30+62+102)=I|g(1+|a)(112.9)=22 {i6}.
159DY cG TI(U)$Note that I|g(1+|a)(62)/I|g(1+|a)(30)=0.11 (1982Vy02) and 0.66
159DY2cG (1971Bo18), so I|g(1+|a)(62) is uncertain.
159DY cL E$From least-squares fit to |g energies.
159DY cL J$From {+159}Dy Adopted Levels, but same are given by 1968Bo18.

159DY N 1.18 14 1.18 14 1.00
159DY cN NR$weighted average of 1.16 {I22}, from requiring that the sum of the
159DY2cN I(|g+ce) values of the transitions deexciting the isomeric state be
159DY3cN 100%; and 1.19 {I20}, from requiring that the sum of the I(|g+ce)
159DY4cN values of the transitions feeding the g.s. be 100%. At each excited
159DY5cN level below the isomer, the intensity feeding the level and that
159DY6cN depopulating it agree to within their uncertainties.
