Abstract

The ground state of the neutron unbound nucleus²⁶O is speculated to have a lifetime in the pico-second regime. In order to determine the decay lifetime of the²⁶O ground state with high sensitivity and precision, a new method has been applied. The experiment was performed in December 2016 at the Superconducting Analyzer for MUlti-particle from Radio Isotope Beams (SAMURAI) at the Radioactive Isotope Beam Factory (RIBF) at RIKEN. A²⁷F beam was produced in the fragment separator BigRIPS and impinged on a W/Pt target stack where²⁶O was produced. According to the lifetime, the decay of²⁶O happens either in or outside the target. Thus, the velocity difference between the decay neutrons and the fragment²⁴O delivers a characteristic spectrum from which the lifetime can be extracted.
