44SC c 1990Me15,1976Co06: Source of {+44}Sc was prepared by the (|g,n)
44SC2c reactions on natural Sc at the Livermore linear accelerator or by the
44SC3c (|a,dxn) reaction on natural Ca metal at the Berkeley 88-inch
44SC4c cyclotron. |g rays were detected with a Ge(Li) detector. Measured E|g,
44SC5c I|g. Deduced levels, branching ratios.
44SC d I|g in 1990Me15 and 1976Co06 are the same but E|g values are different.
44SC2d Value from 1990Me15 are considered to supersede those in 1976Co06
44SC c 1968Wa21: {+44m}Sc produced by irradiation of 40 mg Sc{-2}O{-3} with
44SC2c bremsstrahlung of 40 MeV beam from Darmstadt linear accelerator.
44SC3c NaI(Tl) and Ge(Li) for detecting |g-rays. Measured E|g, I|g, |g|g-coin,
44SC4c |g|g(|q). Deduced levels for {+44}Ca and isomeric state for {+44}Sc.
