175IR  H TYP=FUL$AUT=Jin Wu$CIT=NDS 206, 1 (2025)$CUT=29-Oct-2024$
175IR c  2021Ha32: The parent {+179}Au was produced by the proton induced
175IR2c  spallation of UC{-x} target with E=1.4 GeV protons. Selective
175IR3c  ionization using RILIS at CERN followed by mass separation. Ions of
175IR4c  interest transported to the Windmill decay station. Measured E|a,
175IR5c  I|a, |a(t) using surface barrier silicon detector and E|g, I|g, |a|g,
175IR6c  |g(t) using a low energy Ge detector.
175IR cL E$From E|g and E|a, consistent with Figure 3 of 2021Ha32.
175IR c  2004Ra28: The parent {+179}Au was produced by the |a decay of
175IR2c  {+183}Tl produced with the fusion-evaporation {+144}Sm({+42}Ca,p2n)
175IR3c  reaction at a beam energy of 195 and 200 MeV, using a target
175IR4c  consisting of two (95% enriched) stacked, 500 |mg/cm{+2} thick,
175IR5c  self-supporting {+144}Sm foils. The |a particles were detected with
175IR6c  an 80x35 mm silicon strip detector. Measured E|a.
175IR c  1968Si01: The parent {+179}Au was produced by the {+168}Yb({+19}F,8n)
175IR2c  and {+169}Tm({+20}Ne,10n) reactions. Measured E|a with Surface
175IR3c  Barrier Silicon Detector. Deduced %|a branching.

175IR cA HF$The nuclear radius parameter r{-0}({+175}Ir)=1.5516 {I28} is
175IR2cA deduced from interpolation of radius parameters of the adjacent
175IR3cA even-even nuclides in 2020Si16
175IR cA $E|a=5810 {i15} was detected and tentatively proposed to feed a
175IR2cA 49-keV, (9/2-) level, decayed by a 49|g rays to g.s in 2004Ra28. Both
175IR3cA |a-decay branch and 49|g are not confirmed by 2021Ha32
