New β-decaying state in ²¹⁴Bi

RADIOACTIVITY ^214,214mBi(β^-)[from U(p, X), E=1.4 GeV using RILIS and HRS separator at ISOLDE-CERN facility]; measured Eγ, Iγ, βγ- and γγ-coin, half-lives of decays of ²¹⁴Bi and ^214mBi. ²¹⁴Po; deduced high-spin levels from the decay of ^214mBi, J, π, conversion coefficients for low-energy transitions, multipolarities, Iβ feedings, logft values. ²¹⁴Bi; deduced new β^- decaying isomer, J, π. Comparison with shell-model calculations using H208 and the modified Kuo-Herling particle effective (KHPE) interactions.
