44CA c 1990Me15, 1976Co06: Source of {+44}Sc was prepared by the (|g,n)
44CA2c reactions on natural Sc at the Livermore linear accelerator or by the
44CA3c (|a,dxn) reaction on natural Ca metal at the Berkeley 88-inch
44CA4c cyclotron. |g rays were detected with a Ge(Li) detector. Measured E|g,
44CA5c I|g. Deduced levels, branching ratios, log| {Ift}.
44CA d I|g in 1990Me15 and 1976Co06 are the same but E|g values are different.
44CA2d Value from 1990Me15 are considered to supersede those in 1976Co06
