β decay of ¹³²In and spectroscopy of ¹³²Sn and ¹³¹Sb with the GRIFFIN spectrometer

RADIOACTIVITY ¹³²In(β^-), (β^-n)[¹³²In beam from U(p, X), E=480 MeV, followed by selection of ions through Ion-Guide Laser Ion Source (IG-LIS) at TRIUMF-ISAC]; ^131mSn(β^-)[from ¹³²In β^-n decay]; measured Eγ, Iγ, Eβ, βγ- and γγ-coin, γγ(θ), half-life of ¹³²In decay using GRIFFIN array for γ detection, and SCEPTAR array for β particles. ¹³²In; deduced beta-delayed neutron emission probability or P_n for decay of ¹³²In from total number of decays and γ intensities. ¹³¹Sb, ¹³²Sn; deduced levels, J, π, γ-branching ratios, mixing ratio for a transition in ¹³²Sn, β feedings and logft values for levels in ¹³²Sn. Comparison with VS-IMSRG theoretical calculations for positive-parity states in ¹³²Sn. Comparison with evaluated data in the ENSDF database.
