The long history of the research concerning the possible existence of bound or resonant
states in light multineutron systems, essentially^ 3 3 n and^ 4 4 n, is reviewed. Both the …

The emphasis in this review is on the extent to which theoretical studies have accounted for
the empirical data on the three-nucleon systems. The ground, excited, and continuum states …

The eigenvalue equation to the Faddeev kernel is analytically continued on to nonphysical
sheets adjacent to the real energy axis of the physical sheet. The position of the pole of the …

The observation of 72Zn in a 100 g Zn sample located near a 10 cm W target irradiated by
24 GeV protons is taken as tentative evidence for the production of bound neutral nuclei …

Final-state interactions are common ground between nuclear and particle physics. They are
fruitful because they enable us to infer properties of two (or more)-body systems, or very …

A search for the production of bound tetraneutrons has been carried out with a time
projection chamber using the reaction He 4 (π−, π+) 4 n at &= 80 MeV and at &< 130. No …

When one speaks of the three-body problem, the first characteristic that comes to mind is its
“insolubility.” This describes the situation for the helium atom whose Schrödinger equation …

We report preliminary results of our calculations on the central gross features of the Li 11
nucleus considered as a three body, n 9 system employing two-body separable potentials …

A study of the double charge-exchange reaction π−+ 3He π− π++ 3 n indicates resonant
behavior in the three-neutron system within a few MeV of threshold. The three-neutron data …

Abstract We solve the Tamm-Dancoff equations, using the realistic separable potential of
Tabakin, for the odd-parity excited states of He 4. A comparison is made with results …
