Abstract

A new technique was developed to measure the lifetimes of neutron unbound nuclei in the picosecond range. The decay of O26→O24+n+n 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 O26 was extracted as 4.5-1.5+1.1(stat)±3(syst) ps. This corresponds to O26 having a finite lifetime at an 82% confidence level and, thus, suggests the possibility of two-neutron radioactivity.
