189PO c  2006An36: {+193}Rn produced and identified in {+144}Sm({+52}Cr,3n)
189PO2c  reaction at E=252 MeV; {+144}SmF{-3} rotating target onto a carbon
189PO3c  backing. UNILAC heavy-ion facility at GSI, with SHIP velocity filter
189PO4c  for separating evaporation residues.
189PO c  Several different types of detectors were used by 2006An36.
189PO2c  The decays of the evaporation residues were measured
189PO3c  by implanting residues in a thick 16-strip position-sensitive silicon
189PO4c  detector (PSSD) with a typical FWHM |? 20 keV for |a particles
189PO5c  in 6-8 MeV range. An array of six silicon detectors of similar shape
189PO6c  (BOX detectors), mounted upstream of PSSD detector, was used to
189PO7c  measure the energies of |a, |b and conversion electrons.
189PO8c  Three thin time-of-flight detectors in front of the PSSD and BOX
189PO9c  detectors permitted identification of reaction products from the
189POAc  scattered beam particles; and distinction between the decay events
189POBc  and implantation events through anti-coincidence technique.
189POCc  An additional thick Si detector was installed as a veto detector
189PODc  behind the PSSD detector in an anti-coincidence mode. This allowed
189POEc  distinction between the decays and the punch-through events (from
189POFc  high-energy protons and |a particles produced in the reactions
189POGc  on the carbon backing). For |g rays, a four-fold segmented 'Clover'
189POHc  Ge detector was used behind the PSSD detectors for prompt and delayed
189POIc  |g(residues) coin and/or |a|g coin measurements.
189POJc  Measured |a, |g, |a|g coin, |a(residues) coin, |g(residues) coin.
