162RE D DATA SET COMPLETELY REDONE (DECEMBER, 1997) BY CW REICH TO INCLUDE
162RE2D NEW AND MORE DEFINITIVE DATA FROM 1997Da07
162RE c 1997Da07: {+166}Ir produced in the {+92}Mo({+78}Kr,p3n) reaction, with
162RE2c E({+78}Kr)=384 MeV. Enriched (>97% {+92}Mo) target of thickness
162RE3c 580 |mg/cm{+2}, presumably evaporated onto a 700 |mg/cm{+2} Al
162RE4c backing. The recoil nuclei were separated according to their
162RE5c mass-to-charge ratio in the Fragment Mass Analyzer at the ATLAS
162RE6c accelerator facility. After passing through a thin position-sensitive
162RE7c parallel-grid avalanche counter, located at the focal plane of the
162RE8c analyzer, the recoils were implanted into a double-sided
162RE9c silicon-strip detector. Both position and time correlations between
162REKc the recoils and their decay products were measured, as well as
162RESc energies and intensities of their emitted radiations. Results include
162RENc T{-1/2}, E(p), %p, E|a, %|a.
162RE c 1996Pa01: {+166}Ir produced as a fusion evaporation product in the
162RE2c {+112}Sn+{+58}Ni reaction, with E({+58}Ni)=297 and 329 MeV. The
162RE3c {+112}Sn target (enrichment not given) was |?0.9 mg/cm{+2} thick. The
162RE4c recoil products were separated in flight in the Daresbury recoil mass
162RE5c spectrometer and implanted in a double-sided silicon-strip detector.
162RE6c This detector (energy resolution |<20 keV FWHM) was used to study
162RE7c position and time correlations of the decay events. Measured
162RE8c energies and intensities of the emitted particles and nuclide T{-1/2}
162RE9c values.
162RE c For another study, see 1981Ho10. {+166}Ir produced by {+58}Ni
162RE2c bombardment. |a spectrum of recoil nuclides was measured with a Si
162RE3c detector following velocity selection. 1981HoZM give the same data.
162RE cA HF$The nuclear radius parameter r{-0}({+162}Re)=1.5562 {I69}
162RE2cA is deduced from interpolation (or unweighted average) of radius
162RE3cA parameters of the adjacent even-even nuclides.

166IR DP E COMPUTED FROM THE ENERGY DIFFERENCE, AS REPORTED BY 1997Da07,
166IR2DP OF THE PROTON GROUPS FROM THIS STATE AND FROM THE 166IR GROUND STATE
166IR3DP TO THE 165OS GS.
166IR DP J L=5 PROTON EMISSION TO THE 165OS GS (PROBABLE CONFIGURATION=
166IR2DP |n f{-7/2}) INDICATES THAT THE ODD PROTON IS IN THE |p h{-11/2}
166IR3DP ORBITAL. THE WEAK ^Nordheim RULE FOR THESE TWO ORBITALS SUGGESTS THAT
166IR4DP THE JPI=9+ COUPLING SHOULD LIE LOWEST (1997DAO7).
166IR DP T FROM 1997Da07, ^p(t). OTHERS: 15.2 MS 9, FROM 1997Da07, |a(t)
166IR2DP 12 MS 1, FROM 1996Pa01, |a(t). THIS LATTER VALUE WAS NOT INCLUDED BY
166IR3DP THE EVALUATOR, SINCE THERE IS A POSSIBILITY THAT THE SOURCE PRODUCED
166IR4DP BY 1996Pa01 MIGHT HAVE CONTAINED SOME CONTRIBUTION FROM THE 166IR GS
166IR5DP ACTIVITY (T=10.5 MS).
166IR DP QP COMPUTED FROM EA=6562 6, ASSUMING THAT THE |a TRANSITION
166IR2DP CONNECTS THE GROUND STATES OF THE TWO NUCLIDES. 2003Au03 ALSO GIVE
166IR3DP THIS VALUE.
