The neutron long counter NERO for studies of b delayed neutron emission in the r-process

The neutron long counter NERO was built at the National Superconducting Cyclotron Laboratory (NSCL), Michigan State University, for measuring b delayed neutron-emission probabilities. The detector was designed to work in conjunction with a b delay implantation station, so that b decays and b delayed neutrons emitted from implanted nuclei can be measured simultaneously. The high efficiency of ab...

Enhanced γ-Ray Emission from Neutron Unbound States Populated in β Decay.

Total absorption spectroscopy is used to investigate the β-decay intensity to states above the neutron separation energy followed by γ-ray emission in (87,88)Br and (94)Rb. Accurate results are obtained thanks to a careful control of systematic errors. An unexpectedly large γ intensity is observed in all three cases extending well beyond the excitation energy region where neutron penetration is...

A Preliminary Comparison of MCNP6 Delayed Neutron Emission from

A Description of the Experiment The DNC system at RMCC uses the SLOWPOKE-2 reactor [2] as a source of neutrons. Samples containing 235 U were prepared as acidified aqueous solutions from certified reference standards (natural U standard CRM 4321C, NIST, Gaithersburg, MD, and depleted U standard CRM U005A 0.5064 ± 0.0003 atom% U, New Brunswick Laboratory, Argonne, IL). Each solution was containe...

β-delayed neutron spectroscopy using trapped radioactive ions.

A novel technique for β-delayed neutron spectroscopy has been demonstrated using trapped ions. The neutron-energy spectrum is reconstructed by measuring the time of flight of the nuclear recoil following neutron emission, thereby avoiding all the challenges associated with neutron detection, such as backgrounds from scattered neutrons and γ rays and complicated detector-response functions. (137...
