Beta-delayed neutron spectroscopy using ion traps

ORAL

Abstract

Trapped radioactive ions suspended in vacuum allow for a new way to perform beta-delayed neutron spectroscopy. Decay branching ratios and energy spectra of the emitted neutrons are inferred from a measurement of the nuclear recoil, thereby circumventing the many limitations associated with direct neutron detection. Beta-delayed neutron measurements were carried out for \textsuperscript{137-138,140}I, \textsuperscript{134-136}Sb, and \textsuperscript{144-145}Cs at the Californium Rare Isotope Breeder Upgrade (CARIBU) facility at Argonne National Laboratory. The data collected are needed in many fields of basic and applied science such as nuclear energy, nuclear astrophysics, and stockpile stewardship. Results for the isotopes \textsuperscript{135-136}Sb and \textsuperscript{140}I will be presented. Supported by NSF under PHY-1419765, and U.S. DOE under NEUP 13-5485, DE-AC02- 06CH11357 (ANL), DE-AC52- 07NA27344 (LLNL), and DE-NA0000979 (NNSA).
