We aim to study several nuclei beyond 132Sn, a region where except interplay of single-particle and collective excitations, atypical orbital evolutions, sub-shell gaps and evolving deformation is expected. In particular, we aim to probe the ground and excited states using bg, bgg and bgn measurements at the focal plane of Lohengrin using beta-scintillators, Ge and LaBr3(Ce) detectors as well as our user Si/Ge sandwich and neutron scintillation detectors. Our physics interest lies in resolving the puzzle of the 136Sb ground state and measuring the lifetime of its daughter's low and high-lying states probing their single-particle or collective character. We aim to study for the first time the b decay of 137Sb, identifying the low-spin excitations in 137Te and to determine the position of the 5/2- and 3/2- states in this nucleus. With its subsequent decay firm identification and more about the origin of the first excited 3/2+ and 5/2+ states shall also be possible. Furthermore, the decay of 138Te will give details on the unfixed assignments for its daughter's ground and first excited states. The respective bn channels will also be investigated.
