Abstract

Inclusive energy spectra of protons, deuterons and tritons as well as spectra and angular distributions of two coincident charged particles emitted following stopped negative pion absorption in 6Li and 7Li were measured. Energy and missing mass spectra, angular distributions and yields of two coincident charged particles are presented. Peaks corresponding to quasi-free absorption on different clusters and specific final-state interactions are observed in the coincidence spectra of the Li isotopes. In the dt spectrum of 6Li as well as in the tt spectrum of 7li evidence for 4H formation with a resonance energy of 2.7 MeV and a reduced width of 2.3 MeV is found.

      This is particularly feasible for light nuclei, where the binding limits and large neutron–to–proton ratios can be reached by adding few nucleons to stable isotopes. In hydrogen, experiments have already obtained evidences of 4,5,6,7H isotopes, a chain of four resonances beyond the neutron dripline [2–27]. These systems are found to decay by neutron emission and thus believed to be built on a core of 3H surrounded by neutrons confined by a centrifugal barrier and grouped in pairs.
