Discovered by Roberts et al. beta delayed neutrons are very relevant in reactor control, nuclear astrophysics and nuclear structure. Beta delayed neutron emission is a process that become more a more dominant as we move far away from stability, so its study is crucial for understanding the nuclear structure of very exotic neutron rich nuclei. In this talk, I will present how it is possible to...

The segmented plastic scintillation detector GARi was tested with RI beam in the focal plain F11 of the RIBF accelerator complex. Implantation-decay correlation was obtained based on the reconstructed ion and beta positions on GARi. Known half-lifes in neutron-rich Ar region were used to validate the implantation-decay correlation. Additionally, several new half-lives in this region were...

The neutron-rich $N \sim 126$ region is important to r-process calculations, but difficult to be accessed by experiments. This region is unique for its strong competition between allowed and first-forbidden transitions, which complicates half-life predictions. Besides, the abundances of the third r-process peak elements and actinides are sensitive to half-lives of $N = 126$ isotones....

We study beta decay by using beyond mean field model so called Subtracted second RPA model including 2-particle-2hole configurations on top of 1p-1h configuration. We study also the effect of tensor correlations in beta decay process.
