154HF D   DATA SET UPDATED (FEBRUARY, 2007) BY CW REICH TO INCLUDE NEW T
154HF2D   VALUE AND NEW QA VALUE. SOME INFORMATION WAS ADDED (NOVEMBER, 2008)
154HF3D   DURING THE RESPONSE TO THE REVIEW'S COMMENTS.
154HF c  Production: {+58}Ni bombardment of {+106}Cd using the velocity filter
154HF2c  SHIP (1989Ho12); 290-MeV {+58}Ni ions on isotopically enriched {+102}Pd
154HF3c  target at the Daresbury Recoil Mass Separator (1996Pa01); {+58}Ni
154HF4c  bombardment of {+102}Pd, involving mass separation (2000Ma95).
154HF cA HF$The nuclear radius parameter r{-0}({+154}Hf)=1.558 {I10}
154HF2cA is deduced by assuming HF=1.0 for the ground-state to
154HF3cA ground-state alpha decay branch.

154HF cA E$From 2000Ma95. Note that this is the same as the weighted average of:
154HF2cA 6433~{I30} (1989Ho12); 6442~{I30} (1996Pa01); and 6445~{I3} (2000Ma95).
154HF3dA From this value, one computes Q(|a)=6612~{I3}.
