Study of the deformed beta delayed neutron precursor $^{106}Nb$ with the new neutron tracking detector.*

The neutron energy spectrum measurement of the deformed beta-delayed neutron precursor $^{106}Nb$ has been performed for the first time at Argonne National Laboratory using beams from the CARIBU facility. Neutron emission from the beta decay of implanted $^{106}Nb$ ions was measured with the recently developed neutron detector array called NEXT (Neutron Detector with Xn Tracking). The neutron tracking capability of NEXT provides a significant improvement in energy resolution in neutron time-of-flight measurements. The high intrinsic detection efficiency of NEXT is essential to study decays of neutron-rich nuclei, which are beta-delayed neutron precursors. The results of this measurement and future plans to measure nuclei in this region at CARIBU will be presented.
