175AU c 2017Ba46: The {+179}Tl was produced through the fusion-evaporation
175AU2c reaction {+104}Pd({+78}Kr,p2n){+179}Tl, using a {+78}Kr{+15+} beam of
175AU3c 358 MeV impinging on a self-supporting rotating {+104}Pd target with
175AU4c a thickness and enrichment of 745 |mg/cm{+2} and 92.25%,
175AU5c respectively. The evaporation residues of interest were separated
175AU6c from beam and unwanted reaction products using the gas-filled
175AU7c separator RITU and transported to the focal plane, where the HPGe
175AU8c GREAT spectrometer is located to detect the emitted |g rays. The
175AU9c isotopes of interest were implanted into a 300-|mm-thick double-sided
175AUac silicon strip detectors (DSSDs) placed in the center of the GRETA
175AUbc spectrometer, in which the decay products of |a particles were
175AUcc detected. Measured E|g, E|a, T{-1/2}.
175AU c 2013An10,2010An01: The {+179}Tl was produced in two reactions. First
175AU2c reaction E(p)=1.4 GeV at ISOLDE-CERN, using a target of 50 g/cm{+2}
175AU3c {+238}U. The {+179}Tl was ionized to 1+ charge by the Resonance
175AU4c Ionization Laser Ion Source (RILIS) and mass separated by the High
175AU5c Resolution (HRS) and General Purpose (GPS) Separators. Second
175AU6c reaction E({+40}Ca)=232 MeV provided by the UNILAC of GSI, using a
175AU7c target of |?350 |mg/cm{+2} {+144}Sm, separated by the velocity filter
175AU8c SHIP at GSI. Measured E|g, I|g, E|a, I|a, T{-1/2}, yield using a
175AU9c single Miniball Ge cluster and a DSSD. Deduced J{+|p}, |a branching
175AUac ratio.
175AU c 2002Ro17: The parent {+179}Tl was produced using a projectile of
175AU2c {+78}Kr at E=355 MeV (340 MeV at midtarget) bombarding a target of
175AU3c 90.4% enriched {+202}Pb. The recoil residues were transported to a
175AU4c gas-filled separator and parallel-plate avalanche counters, finally
175AU5c implanted into a Si strip detector. The emitted |g rays were detected
175AU6c with the HPGe detector. Deduced T{-1/2}, corrected for random
175AU7c correlation rates.
175AU c 1998To14: The parent {+179}Tl was produced using a projectile of
175AU2c {+92}Mo at E=420 MeV (404 MeV at midtarget) bombarding a target of
175AU3c {+90}Zr. The recoil residues were transported to a gas-filled
175AU4c separator and parallel-plate avalanche counters, finally implanted
175AU5c into a double sided Si strip detector with 40 in horizontal and 40 in
175AU6c vertical. Measured: E|a, t, I|a.
175AU c 1996Pa01: The parent {+179}Tl was produced from heavy-ion
175AU2c fusion-evaporation reactions. The recoil residues were transported to
175AU3c a mass separator and implanted into a double-sided Si strip detector
175AU4c (FWHM|<20 keV). Measured E|a, parent and daughter T{-1/2}.
175AU c 1983Sc24: The parent {+179}Tl was produced using a projectile of
175AU2c {+92}Mo at E=414-497 MeV bombarding a target of enriched (>95%) Rb-Mo
175AU3c isotopes. The recoil residues were implanted into an array of seven
175AU4c position surface Si detectors. The emitted |g rays were detected with
175AU5c the HPGe detector. Measured E|a, I|a.
