Abstract

The two-neutron unbound systems of ¹⁶Be, ¹³Li, ¹⁰He, and ²⁶O have been measured using the Modular Neutron Array (MoNA) and 4 Tm Sweeper magnet setup. The correlations of the 3-body decay for the ⁶Be and ³Li were extracted and demonstrated a strong correlated enhancement between the two neutrons. The measurement of the ¹⁰He ground state resonance from a ¹⁴Be(-2p2n) reaction provided insight into previous predictions that wavefunction of the entrance channel, projectile, can influence the observed decay energy spectrum for the unbound system. Lastly, the decay-in-target (DiT) technique was utilized to extract the lifetime of the ²⁶O ground state. The measured lifetime of 4.5^+1.1-1.5(stat.)±3(sys.) ps provides the first indication of two-neutron radioactivity.
