Spectroscopy of the ^sup 9^Li isotope in stopped-pion absorption reactions

The origin of the 9Li isotope is sought in missing-mass spectra measured in 11B(π-, d)X, 12C(π-, pd)X, and 14C(π-, dt)X stopped-pion absorption reactions. The parameters of the three observed low-lying excited states coincide with the literature data. A state with excitation energy E x = 9.1 ± 0.1 M...

Zusammenfassung:The origin of the 9Li isotope is sought in missing-mass spectra measured in 11B(π-, d)X, 12C(π-, pd)X, and 14C(π-, dt)X stopped-pion absorption reactions. The parameters of the three observed low-lying excited states coincide with the literature data. A state with excitation energy E x = 9.1 ± 0.1 MeV, lying above the threshold of 9Li decay into 6He + t, is observed for the first time.
