207PB C 1975JA04: Facility: LBL; Source: 211PO as daughter of 211AT, obtained
207PB2C from 209BI(|a,2n) reaction, E(A)=27 MeV; Detectors: one planar Ge(Li)
207PB3C (FWHM=2.3 keV at 1332 keV), one coaxial Ge(Li) (FWHM=2.5 keV at 1332
207PB4C keV), one Si(Li) (FWHM=2.2 keV for 975 keV), one Au-Si surface barrier
207PB5C detector (FWHM=16 keV at 4.8 MeV); Measured: |a-|g coin., E(A), E(|g),
207PB6C conversion electrons; Deduced: level scheme
207PB C 2001Ch66: 211PO source was produced by milking chemically separated
207PB2C 211AT, produced using the 209BI(A,2N) reaction, with |a energies not
207PB3C higher than 28 MeV; Detectors: 70 CM3 coaxial Ge(Li) (FWHM=2.7 keV at
207PB4C 1332 keV); Measured EG, IG; Deduced: IA
