210FR C Others: 1961Gr42, 1979Sc09.
210FR C 2004Ku24: 214AC isotope was produced from 209BI(12C,7N) reaction,
210FR2C E=9.1 MeV/nucleon. Evaporation residues separated from 12C beam by
210FR3C the velocity filter ^SHIP at ^GSI. After separation the residues were
210FR4C implanted into a position-sensitive 16-strip ^PIPS Si detector
210FR5C (FWHM=22 keV at 8 MeV for each strip). In one experiment an HPGe,
210FR6C and in another experiment a Ge clover detector were mounted behind
210FR7C the Si detector. Measured EG, EA, RI, IA, |a-|g/^X-ray COIN. Deduced
210FR8C level scheme, G-ray multipolarity, and JPI.
210FR C 2000He17: Same research group of 2004Ku24. 214AC was produced from
210FR2C 218PA |a decay, 170ER(51V,|a3n) and 209BI(12C,7N) reactions. 16-strip
210FR3C ^PIPS Si detector, two planar Ge-detectors or an HPGe detector.
210FR4C Measured EG, EA, RI, IA, |a-|g/^X-ray COIN. Deduced level scheme.
210FR C 1968Va04: 214AC isotope was produced from 209BI(12C,7N) reaction.
210FR2C Recoiling reaction products were slowed down in a helium atmosphere and
210FR3C collected onto a catcher foil in an adjacent vacuum chamber. Si(Au)
210FR4C surface-barrier detector. Measured EA, IA, EG. Deduced level
210FR5C scheme.
210FR CA E,IA From 2004Ku24, except otherwise noted. EA values of 1968Va04
210FR2CA (in comment section) have been increased by 2 KEV, as recommended in
210FR3CA 1991Ry01 because of changes in calibration energies. IA: deduced
210FR4CA indirectly from |a-|g coin events in 2004Ku24, unless otherwise stated.
210FR CA IA(A)$|a-intensity extracted from singles |a-spectrum (2004Ku24)
210FR CA IA(B)$>0.35 5; 7011|a and 7023|a form a doublet
210FR2CA (2004Ku24) with %I{-|a}=2.1 {I2} from the singles |a-spectrum.
210FR CA HF Using R0(210FR)=1.4701, average of R0(208RN)=1.467 10,
210FR2CA R0(210RN)=1.4552 21, R0(210RA)=1.492 16, and R0(212RA)=1.466 6
210FR3CA (1998Ak04).
210FR CG E Detected in coincidence with alpha particles (2004Ku24).
210FR CG E(Y)$Based upon |a-|g coin data - 2004Ku24 identify the |g-ray as a
210FR2CG transition between excited states, and not feeding the g.s.. The sum
210FR3CG of 41.5 and 121.0 keV is equal to 162.5 keV, which is a tentative
210FR4CG transition from 225 level to 62 level. It is speculated in 2004Ku24
210FR5CG that in a cascade 41.5G and 121.0G could feed the level at 62 keV via
210FR6CG a level at 104.1- or 183.6-keV from 225-keV level.
