203BI cA $The measured {+207}At |a-decay anisotropies of A{-2}=0.153 {I5},
203BI2cA A{-4}=-0.037 {I6} (1997Sc26 and 1996Sc35) suggests a L=2/L=0 mixing
203BI3cA ratio of 0.077 {I3} and a L=4/L=0 mixing ratio of -0.023 {I4}. Hence,
203BI2cA the decay is interpreted as J to J (L=0) with a L=2 component of 0.17%
