155HF D  DATA SET RE-DONE (NOVEMBER, 2003) BY CW REICH
155HF c  Data set includes the XUNDL compilation, by W. D. Kulp (NNDC, BNL) from
155HF2c  2011Sa59
155HF c  2011Sa59: source material produced in the reaction
155HF2c  {+106}Cd({+58}Ni,p3n|g).
155HF2c  Reaction products separated using recoil ion transport unit (RITU)
155HF3c  gas-filled separator and implanted into DSSDs in the Gamma Recoil
155HF3c  Electron Alpha Tagging (GREAT) spectrometer.
155HF3c  Measured |a, protons, |a and delayed |a correlations.
155HF3c  Characteristic alpha decay of the {+159}W ground state and
155HF3c  anti-coincidence with any decay within 20 ms after the initial decay
155HF3c  observed population of both 11/2- and 1/2+ states in {+155}Lu
155HF c  1996Pa01: source material produced in heavy-ion fusion reactions
155HF4c  followed by separation in a recoil mass separator and analysis
155HF5c  using a double-sided Si strip detector.
155HF c  1981HoZM: Sources produced in heavy-ion induced reactions followed by
155HF2c  velocity separation and implantation into position-sensitive
155HF3c  Si detector array
155HF cA HF$The nuclear radius parameter r{-0}({+155}Hf)=1.5566 {I82}
155HF2cA is deduced from interpolation (or unweighted average) of radius
155HF3cA parameters of the adjacent even-even nuclides.

155HF cN BR        From the ratio of calculated half-lives for |a and
155HF2cN for |e+|b{++} decay, as summarized in 1981HoZM. Calculated
