Preparing for beta-delayed neutron emission studies in 78Ni region with VANDLE at RIBF
ORAL
Abstract
The measurement of the beta decay strength distribution in the decay of doubly magic nucleus 78NI was proposed at RIBF RIKEN. The experiment will utilize VANDLE neutron detector combined with the high-efficiency gamma-ray array to measure a complete cascade of the decay to both neutron bound and unbound states in 78Cu. The experiment will provide a critical test of the predictions of the decay strength, which are foundational for the lifetime calculation for the very neutron-rich nuclei in the region of the nuclear chart, where the r-process originates. The new configuration VANDLE detector setup was designed and is mounted at RIBF RIKEN and is ready to experiment. The details and improvements of the detection setups will be presented.
