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.
