148EU c Production: Sm(p,xn|g) E=17-31 MeV
148EU c Measured: E|g, I|g, |g(|q), |g|g coin, |g excitation functions, Ice,
148EUxc |g(t)
148EU c Decay scheme is from 1981Pi10
148EU cG M From conversion electron data; |a(K)exp were normalized to
148EU2cG that of 347|g in {+149}Eu assumed to be M2
148EU cG RI Relative intensity
148EU cL E From a least-squares fit to the E|g data
148EU cL J From adopted levels; supported by |g(|q), |g excitation
148EU2cL functions, and Ice from this data set
148EU cL T T{-1/2}<1.5 ns for excited states other than the isomer
148EU cG MR$If no value given it was assumed |d=1.00 for E2/M1,
148EU2cG |d=1.00 for E3/M2 and |d=0.10 for the other multipolarities

148EU2cL (1980Ba67), and 152 ns {I21} (1995Jo04). 1981Pi10 gives a T{-1/2}=235
148EU3cL ns {I14} which is quoted by 1995Jo04 as the mean life and not the
148EU4cL half-life. The evaluator has adopted this interpretation as it makes
148EU5cL the 1981Pi10 data consistent with other two measurements.
