162W  c  1978Ca11: {+166}Os produced in the {+106}Cd({+63}Cu,p2n) reaction on an
162W 2c  enriched (86.22% {+106}Cd) target and in the {+107}Ag({+63}Cu,4n)
162W 3c  reaction on an enriched (97.87% {+107}Ag) target. E({+63}Cu)=380 MeV.
162W 4c  The {+63}Cu energy was degraded using thin nickel foils to obtain
162W 5c  excitation functions and mass assignments. The reaction products were
162W 6c  transported for study using He-jet techniques. Measured T{-1/2} and
162W 7c  E|a. See also 1977Ca23.
162W  c  1981Ho10: {+166}Os produced by {+58}Ni bombardment. |a spectra measured
162W 2c  with Si detector following separation of the reaction products using
162W 3c  a velocity selector. Report T{-1/2}, E|a and %|a. See also 1981HoZM.
162W  c  1991Se01: {+166}Os produced as a decay product of the {+106}Cd+{+74}Se
162W 2c  reaction, with E({+74}Se)=340 MeV. Enriched (80% {+106}Cd) target of
162W 3c  thickness 500 |mg/cm{+2}. Reaction products were separated using the
162W 4c  Daresbury recoil mass separator and were subsequently implanted into a
162W 5c  position-sensitive Si surface-barrier detector. Reported T{-1/2}.
162W  c  1996Pa01: {+166}Ir produced as a fusion evaporation product in the
162W 2c  {+112}Sn+{+58}Ni reaction, with E({+58}Ni)=297 and 329 MeV. The
162W 3c  {+112}Sn target (enrichment not given) was |?0.9 mg/cm{+2} thick. The
162W 4c  recoil products were separated in flight in the Daresbury recoil mass
162W 5c  spectrometer and implanted in a double-sided silicon-strip detector
162W 6c  (energy resolution |<20 keV FWHM). Reported T{-1/2}, E|a.
162W  c  2015Li24: {+166}Os produced in {+92}Mo({+78}Kr,2p2n),E({+78}Kr)=380
162W 2c  MeV. Measured E|a, recoil-|a-|a-|a, and half-life of ground state of
162W 3c  {+166}Os. Recoiling nuclei were separated using gas-filled RITU
162W 4c  separator and implanted in GREAT spectrometer at K-130
162W 5c  cyclotron facility of the University of Jyvaskyla.
162W  cA HF$The nuclear radius parameter r{-0}({+162}W)=1.559 {I10}
162W 2cA is deduced by assuming HF=1.0 for the ground-state to
162W 3cA ground-state alpha decay branch.
