The rapid neutron capture process (r-process) is a nucleosynthesis process and is responsible for about half of the abundance of elements heavier than iron in the solar system and for most of those abundances in very metal-poor stars. The probability of β-delayed neutron emission is one of the key feature to understand the nature of the r-process nucleosynthesis model. The β-delayed neutron emission is the process in which β decay is followed by a neutron emission. It can occur in the decays of very neutron-rich nuclei when the β-decay energy (Qβ) is greater than the neutron separation energy (Sn) in the daughter nucleus. The combination of the Beta-delayed neutrons at RIKEN (BRIKEN) detector, BigRIPS and Advanced Implantation Detector Array (AIDA) will be used in our experimental setup to study the β-delayed neutron emission in the region (south-east) of Sn132. This research work will provide a basis for building systematics of β-delayed neutron emission probabilities beyond N=82.
