193BI C 1999Sm07: 197AT produced from 165HO(36AR,4N), E=178 MeV; Recoiling
193BI2C fusion-evaporation products were magnetically separated in-flight from
193BI3C the primary beam and fission products using the ^RITU gas-filled recoil
193BI4C separator. The recoils were implanted into a 16-strip Si detector,
193BI5C three Clover-type Ge detectors for prompt |g-ray and another four Ge
193BI6C detectors for delayed |g ray detection. Measured E|g, E|a, and
193BI6C half life using recoil-decay-tagging technique.
193BI C Sources from {+185,187}Re({+20}Ne,xn) (E({+20}Ne)=100-200 MeV
193BI2C (1967Tr06), E({+20}Ne)|<240 MeV (1986Co12)); helium-jet transport;
193BI3C measured E|a, I|a (silicon surface-barrier detectors).
193BI C 2014Ka23: {+197}At obtained from {+201}Fr decay. {+201}Fr produced
193BI2c in {+149}Sm({+56}Fe,p3n), E=275 MeV; Target=370 |mg/cm{+2} thick
193BI3c enriched to 96.9% in {+149}Sm. Evaporation residues were separated
193BI6c using SHIP facility at GSI, and implanted into the detection system
193BI7c consisting of 16-strip position sensitive Si detectors (PSSD),
193BI8c a pack of six Si strip detectors (BOX) at the back to detect escaping
193BI9c |a particles, and three time-of-flight detectors in front of PSSDs.
193BIAc Measured position and time correlations between evaporation residues
193BIBc (Er) and |a events, E|a, half-lives of ground states and isomers of
193BICc {+201}Fr and {+197}At, Er-|a-|a correlations.
