β decay and β-delayed neutron decay of the N=82 nucleus ¹³¹₄₉In₈₂

RADIOACTIVITY ¹³¹In(β^-), (β^-n)[from U(p, F), E=480 MeV]; measured Eγ, Iγ, Iβ^-, γγ-, βγ-, and βγγ-coin, half-lives of 9/2+ ground state, 1/2- and 21/2+ isomers in ¹³¹In, and those of 10+ isomer in ¹³⁰Sn, and (23/2-) isomer in ¹³¹Sn using the GRIFFIN array for γ detection and the SCEPTAR array for β detection at TRIUMF-ISAC facility. ^130,131Sn, ¹³⁰Sb; deduced levels, J, π, conversion coefficient, multipolarity, configurations, β feedings, delayed-neutron emission probabilities P_n for 21/2+ isomer, and combined P_n for 1/2- isomer and 9/2+ g.s. for the decays of ¹³¹In activities. Comparison with previous experimental results.
