48V DG CC$FROM BrIcc v2.3e (17-Jun-2020) 2008Ki07, "Frozen Orbitals" appr.
48V c 1979PrZU: measured E|g, I|g, |g(t), E|b{++}, I|b{++}, E(ce), I(ce).
48V 2c Deduced parent T{-1/2}, conversion coefficients, |g-ray
48V 3c multipolarities. Orange |b spectrometer for conversion electrons and
48V 4c other unspecified detectors.
48V c 1968We01: source was prepared by {+50}Cr(d,4n) with |?45 MeV deuteron
48V 2c beam from the isochronous cyclotron at the Kernforschungszentrum
48V 3c Karlsruhe. Measured |g|g(|q) and |g|g-polarization correlation with
48V 4c NaI(Tl) scintillators and plastic scintillator. Deduced parity for the
48V 5c 308 level, multipolarity and mixing ratio for 112|g.
48V c 1967Au02: source was prepared by {+47}Ti(|a,3n) with |?50 MeV alpha
48V 2c beam from the Bonn synchrocyclotron. Measured |g|g(|q,H,t) using
48V 3c NaI(Tl) and Ge(Li) detectors. Deduced T{-1/2}, |m for the 308 level.
48V c Others:
48V c 1987Ra19: source was prepared by {+46}Ti(|a,2n) at the Physikalisches
48V 2c Institut. measured |g|g(|q,H,t). Deduced g factor for the 308 level.
48V c 1971Bo13: source was prepared by {+47}Ti(|a,3n) at the Lewis Research
48V 2c Center. Measured |g|g(t). Deduced lifetime of the 308 level.
48V c 1969PaZT: source was prepared by {+46}Ti(|a,2n) and {+56}Fe(p,xnyp)
48V 2c at Carnegie-Mellon University. Measured |g|g(|q,H,t). Deduced T{-1/2}
48V 3c and |m for the 308 level, mixing ratio for 112|g.
48V cE $The decay scheme is considered incomplete due to a large gap (|?1.2
48V 2cE MeV) between Q(|b{+-})value=1657 keV {I7}(2021Wa16) and the highest
48V 3cE observed level at E=421 keV
48V cE TI$The total feeding is 97.6% {I21} and the missing feeding of 2.4%
48V 2cE {I21}, if significant, could be due to unobserved transitions from
48V 3cE higher levels not seen in the decay measurements.
48V cG E,RI$From 1979PrZU, using {+152}Eu as standard. {+48}Cr activity
48V 2cG determined from the decay of {+48}V.
48V cG M,MR$From |a(exp) (1979PrZU) and/or |g|g(|q,pol) (1968We01). Values
48V 2cG are adopted in Adopted Gammas.
48V cL E$From a least-squares fit to |g-ray energies.
48V cL J,T$From Adopted Levels. Supporting arguments or other values from
48V 2cL this dataset are given under comments.

48V cE TI$3 {I3} from |g+ce intensity balance would result in a log {Ift}=5.9
48V 2cE {I5}, which seems low for a second forbidden non-unique transition.
