Popis:	The structure of 131 Te has been investigated with the 130 Te( n , γγ ) 131 Te reaction using thermal neutrons and with the 130 Te( d , p ) 131 Te reaction using polarized deuterons with energy E d =18 MeV. About 290 levels were identified in most cases including spin, parity and γ -decay. The γ -decay scheme after neutron capture is essentially complete containing about 100% of the decay of the capture state and about 100% of the population of the 11/2 − isomer and of the ground state. The scheme includes 42 primary transitions with energies between 750 keV and 2500 keV. The experimental level scheme is compared with predictions of the Interacting Boson–Fermion model (IBFM) and of the Quasiparticle Phonon Model (QPM). The isomeric ratio of the 11/2 − isomer at 182.31(5) keV was determined to be 0.054(2). The neutron binding energy is 5929.38(6) keV. The total thermal neutron capture cross section was found to be 186(13) mbarn.
