¹⁴⁵Ba and ^{145, 146}La structure from lifetime measurements

RADIOACTIVITY ^145,146Cs(β^-), (β^-n)[from U(p, F), E=478 MeV from TRIUMF cyclotron, followed by mass separation of fragments of interest in the TRIUMF-ISAC facility, and ions stopped in a mylar tape]; measured Eγ, half-lives of levels by βγγ(t) fast timing method using GRIFFIN array with 12 HPGe clover detectors, four cylindrical LaBr₃(Ce) scintillators for fast timing of γ rays, SCEPTAR array of ten plastic scintillators for β tagging, and a thin fast plastic scintillator for β timing signal. ^144,145,146Ba, ^145,146La; deduced levels, J, π, T_1/2 of excited states, B(E1), B(M1), B(E2). Comparison with previous experimental results.
