162HF c  The experimental methods were:
162HF c  1975To05: {+166}W produced by {+156}Dy({+16}O,6n) reaction on enriched
162HF2c  (12.6%) target. |a spectra measured with Si surface-barrier detectors.
162HF3c  Excitation function used to identify mass.
162HF c  1979Ho10: {+166}W produced in {+58}Ni bombardment of {+108}Pd target.
162HF2c  |a spectra measured with Si detector following velocity selector.
162HF3c  |a-decay sequences used to determine mass.
162HF c  1989Hi04: {+166}W produced in the {+136}Ba({+36}Ar,6n) reaction at
162HF2c  {+36}Ar energies from 177 MeV to 214 MeV. Targets were {+136}BaF{-2}
162HF3c  (93% enrichment), 1.2 and 1.3 mg/cm{+2} thick, and backed with C
162HF4c  foils, 30 and 34 |mg/cm{+2} thick. Recoil nuclides were transported
162HF5c  using a He-jet tape-transport system for analysis. |a particles were
162HF6c  counted using 450 mm{+2} surface-barrier detector. Mass assignment was
162HF7c  determined from excitation functions. T{-1/2} was obtained from
162HFxc  multiscaled spectra.
162HF c  See also 1975IjZZ and 1981HoZM for other reports on same results.
162HF cA HF$The nuclear radius parameter r{-0}({+162}Hf)=1.516 {I19}
162HF2cA is deduced by assuming HF=1.0 for the ground-state to
162HF3cA ground-state alpha decay branch.
