Nuclear structure of ¹⁵⁷Sm via β^- decay of ¹⁵⁷Pm

RADIOACTIVITY ¹⁵⁷Pm(β^-); measured decay products, Eγ, Iγ, β-γ-γ-coin.; deduced energy levels, J, π, T_1/2, an allowed spin-flip transition with the relatively low log ft value. Comparison with available data. The CARIBU source, the SATURN moving tape system.
