Abstract	We propose to study beta-delayed neutron emission from $^{134}$In using Isolde Decay Station neutron and gamma detectors and new high-resolution neutron detector NEXT. The experiment aims to perform high-statistics and high-resolution spectroscopy of neutrons, which are emitted from excited states in $^{134}$Sn and $^{133}$Sn. The experiment addresses multiple goals relevant to nuclear structure and astrophysics. It will provide data which will constrain the models of beta decays and statistical particle emission near $^{132}$Sn. The focus of this experiment will be to study two-neutron emission from excited states in $^{134}$Sn. The relatively large probability of this process will enable the identification of the neutron single-particle i$_{13/2}$ state in $^{133}$Sn, which will be populated in the neutron emission from $^{134}$Sn; it is predicted to be neutron unbound.
