A new technique was developed to measure the lifetimes of neutron unbound nuclei in the picosecond range. The decay of was examined as it had been predicted to have an appreciable lifetime due to the unique structure of the neutron-rich oxygen isotopes. The half-life of was extracted as . This corresponds to having a finite lifetime at an 82% confidence level and, thus, suggests the possibility of two-neutron radioactivity.
