“…4,7. In addition, it is not kinematically consistent with the breakup of 14 Be into 10 Be+ 3,4 n, as a low energy multineutron (11)(12)(13)(14)(15)(16)(17)(18) MeV/N) should be associated with a high energy 10 Be. In the following the discussion is therefore limited to the 6 remaining events.…”

“…These searches have relied on the very low cross-section (typically ∼ 1 nb) double-pion charge exchange (DπCX) [14,15,16] and heavy-ion multinucleon-transfer reactions [17,18,19,20]. Again no conclusive evidence for a bound A n or resonant states has been found in these studies.…”

“…We have subsequently considered the analysis of the energies assuming that 10 Be+ 4 n breakup took place. As the tetraneutron energy has been restricted to [11][12][13][14][15][16][17][18] MeV/N and the 14 Be beam energy is around 30 MeV/N, 10 Be fragments in coincidence with 4 n should have energies per nucleon higher than the beam. The resulting total kinetic energy ( Fig.…”

“…[9]) therefore does not exclude the possible existence of a very weakly bound 4 n. Experimentally, no limit has yet been placed on the binding energy of 4 n (or any other A n). Rather only limits on the production cross-sections could be estimated from twostep [10,11,12,13] or direct reactions [14,15,16,17,18,19,20]. In this paper, a new technique to produce and detect neutron clusters is presented.…”

A new approach to the production and detection of bound neutron clusters is presented. The technique is based on the breakup of beams of very neutron-rich nuclei and the subsequent detection of the recoiling proton in a liquid scintillator. The method has been tested in the breakup of 11 Li, 14 Be and 15 B beams by a C target. Some 6 events were observed that exhibit the characteristics of a multineutron cluster liberated in the breakup of 14 Be, most probably in the channel 10 Be+ 4 n. The various backgrounds that may mimic such a signal are discussed in detail.

“…are almost at the limits of present experimental capabilities due to the limited radioactive beam intensities and extremely low multi-neutron detection efficiency. In the early search for 3 n and 4 n using double-charge-exchange reactions (π − , π + ) [29][30][31] and multinucleon-transfer reactions [32][33][34][35], strong neutron correlations within the populated multi-neutron systems could be inferred from the observed missing-mass spectrum, but these experiments fall short of being conclusive on the presence of neutron cluster states.…”

Formation of neutron clusters from strongly correlated neutrons has become one of the hottest topics in nuclear physics. They lie at the heart of understanding the exotic structure of nuclei around the neutron drip line and provide an important basis for testing nuclear interactions due to the absence of Coulomb interaction and further developing theoretical models. Moreover, neutron clusters composed purely of neutrons could serve as a mini prototype of neutron matter to study the still elusive properties of the extremely neutron-rich nuclear matter, building a bridge between finite nuclei and neutron stars. In this paper, we will briefly review the recent highlights of experimental and theoretical works on neutron clusters.
