In a recent paper --F.M. Marques et al, PRC 65 (2002) 044006-- a new approach to the production and detection of free neutron clusters was proposed and applied to data acquired for the breakup of 14Be. Six events that exhibited characteristics consistent with a bound tetraneutron were observed in coincidence with 10Be fragments. Here, two issues that were not considered in the original paper are addressed: namely the signal expected from a low-energy 4n resonance, and the detection of a bound 4n through proccesses other than elastic scattering by a proton. Searches complementary to the original study are also briefly noted.

    The authors reconcile conflicting tetraneutron reports by proposing that different experiments populated a bound ground state and an unbound first excited state of four neutrons.

    This review summarizes recent quasi-free knockout experiments that find surface-localized dineutron correlations in Borromean nuclei, a weak halo in 17B, evidence for a tetraneutron resonance, and an alpha-2n-alpha cl...
