191BI c  2013Ny01: measured half-life and E|a, recoil-|a correlated decay
191BI2c  measurements at Jyvaskyla cyclotron facility using RITU separator
191BI c  2003Ke04,2005Ke10: Production of {+195}At by {+142}Nd({+56}Fe,p2n),
191BI2c  E(lab)=255-268 MeV. The evaporation residues formed in
191BI3c  the fusion reaction were separated using the RITU gas-filled mass
191BI4c  separator and implanted into a position-sensitive Si strip
191BI5c  detector. A multiwire proportional avalanche gas counter was used to
191BI6c  discriminate |a-ray particles from other signals in the Si detector.
191BI7c  A Compton-suppressed, 40% relative efficiency, Ge detector was used
191BI8c  for prompt |a-|g coincidence measurements.
191BI c  1999Ta20: {+169}Tm({+36}Ar,|a6n), E=215 MeV. RIKEN ring cyclotron.
191BI2c  Recoil reaction products separated with the gas-filled
191BI3c  recoil separator GARIS. Detection of recoil fragments and decay |a
191BI4c  rays using two-dimensional position-sensitive Si detector at the focal
191BI5c  plane. Microchannel plate placed before this detector allows to
191BI6c  distinguish evaporation residues from alpha particles. RDT method.
191BI7c  Analyze correlated recoil-alpha1-alpha2 decay chains.
191BI cA E,IA      |a-ray energy and relative intensity from

191BI cA HF$A r{-0}({+191}Bi)=1.548 {i10} is obtained is deduced from
191BI2cA interpolation (or unweighted average) of the r{-0} values for the
191BI3cA neighboring even-Z, N=108 isotones: r{-0}({+190}Pb)=1.511 {i4},
