Search for light neutron-rich isotopes in stopped pion absorption

Abstract

The results based on the spectroscopy of superheavy hydrogen isotopes (⁴⁻⁷H), heavy helium isotopes (^6,7He), and heavy lithium isotopes (⁷⁻¹²Li) produced in stopped pion absorption by light nuclei were analyzed. Search for nuclear states was performed in inclusive and correlation measurements of missing mass spectra. A broad range of excitation energies studied in correlation measurements provided the possibility of search for isobaric analog states and cluster resonances. A comparison with experimental and theoretical results of other authors was conducted.
