32SI DG CC$FROM BrIcc v2.3e (17-Jun-2020) 2008Ki07, "Frozen Orbitals" appr.
32SI c 1986Du07: {+32}Al source was produced by fragmentation of 60
32SI2c MeV/nucleon {+40}Ar beam on a 190 mg/cm{+2} Be target, separated by
32SI3c the LISE spectrometer, and implanted into a thin movable film. |b
32SI4c particles were detected with a plastic scintillator and |g rays were
32SI5c detected with a Ge detector. Measured E|g, I|g, |b|g-coin, |b|g(t).
32SI6c Deduced parent T{-1/2}.
32SI c 1984Gu19: {+32}Al source was produced by fragmentation of a 30 g/cm{+2}
32SI2c iridium target by 10 GeV protons from the CERN synchrotron, separated
32SI3c by a mass spectrometer, and transported into a thin stainless steel
32SI4c tube. |g rays were detected with Ge(Li) detectors and delayed-neutrons
32SI5c were detected with a {+3}He proportional counter. Measured E|g, I|g.
32SI6c Deduced levels, |b-decay and |g-ray emission probabilities.
32SI c 1982Mu08: identified {+32}Al isotope and measured T{-1/2} at LBL.
32SI c Others: measured T{-1/2}: 2017Ha23, 2005Ue01, 2008ReZZ (1995ReZZ)
32SI c From RADLIST code, the total energy released is 12990 keV {I150},
32SI2c compared with 12887 keV {I65} from Q-value=12978 {I7} and branching of
32SI3c 99.3% for population of levels in {+32}Al by |b{+-} decay
32SI c Placements of |g transitions are based on those in Adopted Levels,
32SI2c Gammas. No decay scheme is given in 1986Du07
32SI c This decay scheme is considered incomplete due to a large gap between
32SI2c the highest observed level at E=5786 and the Q-value=12978 {I7}
32SI3c (2021Wa16). S(n)=9200.0 {I3} and S(2n)=15787.36 {I30} (2021Wa16) for
32SI4c {+32}Si
32SI cB IB,LOGFT$|b intensity from |g intensity balance at each level, unless
32SI2cB otherwise noted. Quoted values should be considered as approximate
32SI3cB due to incomplete decay scheme.
